Asim said: I asked Sayyiduna Anas bin Malik (may Allah be pleased with him) about Qunoot, so he said: It is before bowing (ruku‘). I said: So-and-so thinks that you have said Qunoot is after bowing. Sayyiduna Anas (may Allah be pleased with him) said: He has lied. Then he narrated the hadith that the Noble Prophet (peace and blessings be upon him) recited Qunoot after bowing for a month, or he said: For a month, he supplicated against a tribe of Banu Sulaym.
