The textual proofs of our Imams in all of this are overwhelming and it's meaning successively transmitted .The contents are clear to refute their opposition to it (the basmala) like the saying of Imam Abu 'Abd Allah al-Sadiq, peace be upon him, "What is it with them?
They depend on the greatest verse in the book of God, the Almighty, the most Glorious, and they claim it is an innovation if they declare `In the name of God the most merciful, the most beneficent' openly." Our argument is based on the path of the masses, and its authentic traditions which are many: First: What has been established from Ibn Jurayj from his father from Sa`id b.
Jubayr from Ibn `Abbas on the saying of the most High: "We have given you the seven most repeated verses." He said: "The opening [chapter] of the book, in the name of God most beneficent, most compassionate; Praise be to the Lord of the Universe and he recited the chapter." Ibn Jurayj said: "I said to my father: `Did Sa'id tell you from Ibn `Abbas that he said: `In the name of God most merciful, most beneficent' is a verse?' He replied: `Yes.'" This hadith has been reported by al-Hakim in his al-Mustadrak and al-Dhahabi in his al-Talkhis; they have both declared that its chain of transmission (isnad) is intact.
Second: What has been correctly reported from Ibn `Abbas. He said: "When Gabriel used to come to the Prophet (S), and would recite `In the name of God most merciful, most beneficent' he would know that it was a chapter [to be revealed]." Third: What has also been correctly reported from Ibn `Abbas who said: "The Prophet did not use to know the end of a chapter until `In the name of God most merciful, most beneficent' was revealed." Fourth: What has also been correctly reported from him: "The Muslims did not know the end of a chapter until `In the name of God most merciful, most beneficent' was revealed.
When `In the name of God most merciful, most beneficent' was revealed they realized that the chapter had ended." Fifth: What has been correctly reported from Umm Salama: She said: "The Prophet (S) used to recite `In the name of God most merciful, most beneficent, Praise be to God the Lord of the Universe' to the end of the chapter, he would recite it word by word." It is also reported from Umm Salama by another chain that she said: "Indeed the Prophet of God (S) would recite in the prayer `In the name of God most merciful, most beneficent' and would count it as a verse.
