Hajjaj (may Allah have mercy on him) said: I asked Ata (may Allah have mercy on him) about the fasts of the expiation of an oath. He said: If he wishes, he may leave gaps. I said: In the recitation of Abdullah (may Allah be pleased with him) there are the words "mutatabi'at" (consecutive). He said: Then we submit to the Book of Allah.
