He said: He recommended with the Book of Allah.
He said: He recommended with the Book of Allah.”[^3] So no reference is there to a hadith uttered by the Messenger of Allah, saying in it: "I am leaving behind among you two precious things (Thaqalayn): the Book of Allah and my Sunnah." And if supposedly such a hadith is there in some books, it would be to no avail since unanimity was, as mentioned before, to the contraty. Further, should we investigate the hadith.
"The Book of Allah and my Sunnah," we will verily see it not congruous with truth, neither through quoting (naql) nor reason ( Aql ). For refuting it there are several causes: First: The historians and traditionists concur that the Messenger of Allah (S) has forbidden anyone from writing down his traditions, and no one could claim that he was inscribing the Prophetic Sunnah during his lifetime.
The Messenger’s saying"I am leaving behind among you the Book of Allah and my Sunnah" then can never be reasonable. And concerning the Book of Allah, it is inscribed and preserved in the bossoms of men, in a way that any Companion can refer to the Qur’ān, even though being not among the memorizers.
But as regards the Prophetic Sunnah, there is nothing inscribed or compiled during the Prophet’s lifetime, and the Prophetic Sunnah as is widely known and agreed upon, being whatever said, or done or determined by the Messenger (S). And as is known too, the Messenger never used to gather his for teaching them the Prophetic Sunnah, but rather he used to address them, in all occcasions, with the attendance of some or only one of his .
In this case, how would the Messenger say to them, I am leaving behind among you my Sunnah?? Second Cause: When the Messenger of Allah became in a low state of health, three days before his death, he asked to bring him the scapula and inkhorn, so as to write a book after which they would never go astray. Thereat ‘Umar ibn al-Khattāb said: The Messenger of Allah is hallucinating, and we are sufficed with the Book of Allah.
[^4] Had the Messenger (S) told them previously: I am leaving behind among you the Book of Allah and my Sunnah, it would have been infeasible for ‘Umar to say: The Book of Allah is sufficient for us!, as in this case he with the Sahābah sharing his opinion, would be renegading against the Messenger of Allah, the fact that would never be approved of by Ahl al-Sunnah.
