It is narrated from Sayyiduna Anas (may Allah be pleased with him): "When one of you becomes drowsy (during the prayer), let him leave (the prayer) until he knows what he is doing." Ayyub (may Allah have mercy on him) relates that the book of Abu Qilabah (may Allah have mercy on him) was read out to us, in which he had recorded this narration through Sayyiduna Anas (may Allah be pleased with him).
