If you don't mind, I have copy and pasted a passage compiled by a friend of mine, which will give you a pretty comprehensive exploration on Baha'i perspectives on the Hadiths. In short, we generally reject most of them. They are less authentic than the Quran itself.
Here is a compilation of quotations that Baha'is can use to explain the general Baha'i position about the authenticity of hadiths. To make a long story short, the Qur'an is authentic(though obviously some people have distorted its meaning), hadiths quoted by Baha'u'llah and 'Abdu'l-Baha are authentic, other hadiths may or may not be authentic, large scale falsification of hadiths was perpetrated by the Umayyad Caliphs, the Baha'i Faith is protected from becoming falsified because we don't view Baha'i "pilgrim's notes" as authoritative.
"For instance, the Qur'án was an impregnable stronghold unto the people of Muhammad. In His days, whosoever entered therein, was shielded from the devilish assaults, the menacing darts, the soul-devouring doubts, and blasphemous whisperings of the enemy. Upon him was also bestowed a portion of the everlasting and goodly fruits -- the fruits of wisdom, from the divine Tree. To him was given to drink the incorruptible waters of the river of knowledge, and to taste the wine of the mysteries of divine Unity.
All the things that people required in connection with the Revelation of Muhammad and His laws were to be found revealed and manifest in that Ridvan of resplendent glory. That Book constitutes an abiding testimony to its people after Muhammad, inasmuch as its decrees are indisputable, and its promise unfailing. All have been enjoined to follow the precepts of that Book until "the year sixty"[1] -- the year of the advent of God's wondrous Manifestation. That Book is the Book which unfailingly leadeth the seeker unto the Ridvan of the divine Presence, and causeth him that hath forsaken his country and is treading the seeker's path to enter the Tabernacle of everlasting reunion. Its guidance can never err, its testimony no other testimony can excel. All other traditions, all other books and records, are bereft of such distinction, inasmuch as both the traditions and they that have spoken them are confirmed and proven solely by the text of that Book. Moreover, the traditions themselves grievously differ, and their obscurities are manifold.
[1 The year 1260 A.H.]
Muhammad, Himself, as the end of His mission drew nigh, spoke these words: "Verily, I leave amongst you My twin weighty testimonies: The Book of God and My Family." Although many , the year of the Báb's Declaration. traditions had been revealed by that Source of Prophethood and Mine of divine Guidance, yet He mentioned only that Book, thereby appointing it as the mightiest instrument and surest testimony for the seekers; a guide for the people until the Day of Resurrection.
With unswerving vision, with pure heart, and sanctified spirit, consider attentively what God hath established as the testimony of guidance for His people in His Book, which is recognized as authentic by both the high and lowly. To this testimony we both, as well as all the peoples of the world, must cling, that through its light we may know and distinguish between truth and falsehood, guidance and error. Inasmuch as Muhammad hath confined His testimonies to His Book and to His Family, and whereas the latter hath passed away, there remaineth His Book only as His one testimony amongst the people."
(Baha'u'llah, The Kitab-i-Iqan, p. 200)
Now we come to Muhammad. Americans and Europeans have heard a number of stories about the Prophet which they have thought to be true, although the narrators were either ignorant or antagonistic: most of them were clergy; others were ignorant Muslims who repeated unfounded traditions about Muhammad which they ignorantly believed to be to His praise.
Thus some benighted Muslims made His polygamy the pivot of their praises and held it to be a wonder, regarding it as a miracle; and European historians, for the most part, rely on the tales of these ignorant people.
For example, a foolish man said to a clergyman that the true proof of greatness is bravery and the shedding of blood, and that in one day on the field of battle a follower of Muhammad had cut off the heads of one hundred men! This misled the clergyman to infer that killing is considered the way to prove one's faith to Muhammad, while this is merely imaginary. The military expeditions of Muhammad, on the contrary, were always defensive actions
...
Beyond this fact, all the narrations of the Muslims, Christians and others are simply fabrications, which have their origin in fanaticism, or ignorance, or emanate from intense hostility. For example, the Muslims say that Muhammad cleft the moon, and that it fell on the mountain of Mecca: they think that the moon is a small body which Muhammad divided into two parts and threw one part on this mountain, and the other part on another mountain. Such stories are pure fanaticism. Also the traditions which the clergy quote, and the incidents with which they find fault, are all exaggerated, if not entirely without foundation.
(Abdu'l-Baha, Some Answered Questions, p. 18)
They must strive to obtain, from sources that are authoritative and unbiased, a sound knowledge of the history and tenets of Islam -- the source and background of their Faith -- and approach reverently and with a mind purged from preconceived ideas the study of the Qur'án which, apart from the sacred scriptures of the Bábí and Bahá'í Revelations, constitutes the only Book which can be regarded as an absolutely authenticated Repository of the Word of God. They must devote special attention to the investigation of those institutions and circumstances that are directly connected with the origin and birth of their Faith, with the station claimed by its Forerunner, and with the laws revealed by its Author.
(Shoghi Effendi, The Advent of Divine Justice, p. 49)
The history of religion clearly illustrates the misunderstanding, division and error that have resulted from reliance on verbal statements as a source of authoritative knowledge of religious teachings. One of the precious bounties of this Dispensation is that the door has been closed, clearly and unambiguously, to such a source of problems. In response to a question, the Master wrote:
"Thou hast written concerning the pilgrims and pilgrim's notes.
Any narrative that is not authenticated by a Text should not be
trusted. Narratives, even if true, cause confusion. For the people of
Baha, the Text, and only the Text, is authentic." (Translated extract
from a previously-untranslated Tablet of 'Abdu'l-Bahá)
(International Teaching Centre, 1984 Jul 01, Concerns about Retributive Calamity)
A passing reference was made earlier[1] to a nefarious scheme which Mu'awiyah calculated would bring 'Ali into disrepute and besmirch his memory. Mu'awiyah had already instituted a daily ritual of cursing 'All from the pulpit. Next, he bribed some of his minions, who had known. the Prophet and had been with Him, to engage in blasphemous forgery. These despicable men, such as Mughirah and Abu-Hurayrah, opened the field, under Mu'awiyah's direction, to the corruption of doctrine, text, belief and practice. Their deeds were heinous, but their lies can, on the whole, be easily detected. Unfortunately they had their imitators, until faked traditions flooded an eager market. In this a number of Sh'iah apologists must bear their share of blame. There is a vast corpus[2] of genuine traditions that have come down from the Prophet and from His descendants -- the Imams of the Legitimists, the Sh'iahs -- but there are also a great many which are spurious, some blasphemous, others only ridiculous. Incitement to forgery is yet another misdeed of the founder of the Umayyad dynasty.
[1 See p.191. ]
[2 The four great compilations of traditions are: the Sahih of al-Bukhari (d. 870); the Sahih of Muslim, a native of Nishapur in the province of Khurasan (d. 875); the Sahih of at-Timidhi (d. 892); and the Sahih of an-Nisa'i (d. 914). As-Sahih means the 'Genuine'.]
(H.M. Balyuzi, Muhammad and the Course of Islam, p. 192)
Mu'awiya designed an Umayyad policy. The Umayyad rulers after him followed that policy. They (i.e., the Umayyads) wanted to make themselves lords. They wanted to show the people that they had all laudable qualities. So generosity, clemency, cleverness, bravery, and eloquence belonged to them, not to the people. In other words the Umayyads wanted to denote that these qualities were some of their special talents. The Umayyads did their best to fix this intentional policy. Thus they made a false history that was full of a series of fabricated traditions, made-up stories, various lies, and baseless claims. Moreover, they ordered the hireling preachers and the teachers of the schools in all Muslim countries to study the Umayyad hopes including false praise or fake slander.[13]
(quoted from an older version of the wikipedia article about the Umayyad Caliphate)
This is the Day when the loved ones of God should keep their eyes directed towards His Manifestation, and fasten them upon whatsoever that Manifestation may be pleased to reveal. Certain traditions of bygone ages rest on no foundations whatever, while the notions entertained by past generations, and which they have recorded in their books, have, for the most part, been influenced by the desires of a corrupt inclination. Thou dost witness how most of the commentaries and interpretations of the words of God, now current amongst men, are devoid of truth. Their falsity hath, in some cases, been exposed when the intervening veils were rent asunder. They themselves have acknowledged their failure in apprehending the meaning of any of the words of God.
Our purpose is to show that should the loved ones of God sanctify their hearts and their ears from the vain sayings that were uttered aforetime, and turn with their inmost souls to Him Who is the Day Spring of His Revelation, and to whatsoever things He hath manifested, such behavior would be regarded as highly meritorious in the sight of God....
(Baha'u'llah, Gleanings from the Writings of Baha'u'llah, p. 171)
Please God thou wilt turn thine eyes towards the Most Great Revelation, and entirely disregard these conflicting tales and traditions.
(Baha'u'llah, Gleanings from the Writings of Baha'u'llah, p. 174)
One very important point to consider.
According to Shoghi Effendi, the Guardian of the Baha'i Faith, westerners are the victims of a great deal of misinformation about Islam. The Baha'i version of Islam is the extreme opposite of the version of Islam that Muslim dictators, terrorists and violent bigots endorse.
"There is so much misunderstanding about Islam in the West in general that you have to dispel. Your task is rather difficult and requires a good deal of erudition. ...
"The truth is that Western historians have for many centuries distorted the facts to suit their religious and ancestral prejudices. The Bahá'ís should try to study history anew, and to base all their investigations first and foremost on the written Scriptures of Islam and Christianity."
