They contain what is lean and what is fat...
They contain what is lean and what is fat, and Shī’ahs do not consider all the narratives in these books as being accurate, for the Shī’ahs see no book which can be compared with the Book of Allāh in as far as accuracy is concerned as is the case with both Shaykhs, namely al-Bukhāri and Muslim, with regard to their Sahīh books.
For example, in the book titled Masādir al-Hadīth ‘inda al-Shī’a al-Imāmiyya (sources of hadīth according to Imāmite Shī’ahs) by the critic Sayyid Muhammad Husayn al-Jalāli, who classifies the traditions in Al-Kāfi , we read the following: “The number of ahādīth in it is 16,121 of which 9,485 are weak, 114 are good, 118 are confirmed, 302 are strong and 5,702 are authentic.” This clearly demonstrates how Shī’ah scholars themselves consider thousands of ahādīth in Al-Kāfi ; so, where is this “fact” which comes out of the mouths of some liars such as Zahir and al-Khateeb who claim that Al-Kāfi is regarded by the Shī’ahs just as al-Bukhāri’s Sahīh is regarded by the Sunnis, then they claim that its title is ‘ Sahīh al-Kāfi”?!
This is an outrageous lie which they repeat in their poisoned books with the objective to mislead the reader by labeling weak traditions which they derived from Al-Kāfi or other Shī’ah books of hadīth as “authentic” in order to use this as an argument against them and to indict them...
Both Parties’ Stand Regarding The Prophet’s Infallibility While some people with vested interested in addition to some liars circulate erroneous rumors by saying that the Shī’ahs prefer their Imāms over the Messenger of Allāh (ṣ), as many Sunnis think, I have found, from my research, that the Shī’ahs sanctify the Prophet (ṣ) to a degree that is by far greater than that viewed by the Sunnis.
Shī’ahs sanctify the Sunnah of the Prophet (ṣ) and are of the view that anyone who denies a ruling mandated by the Prophet (ṣ) is an apostate. They see the Prophet (ṣ) as the very best of the first generations and of the last. They simply regard upholding the Twelve Imāms from among Ahlul Bayt (‘a) based on their being the most authentic to transmit the Sunnah of the Prophet (ṣ). They reject any and all doubts and hearsay about the Prophet’s infallibility.
In their view, he is infallible with regard to the matters relevant to the creed and to life, prior to his Prophetic mission and thereafter.
