It is narrated from Sayyiduna Ali (may Allah be pleased with him) that he and Sayyidah Fatimah (may Allah be pleased with her) came to the Noble Prophet (peace and blessings be upon him) to ask for a servant from among the captives, so that the servant could do some of the work and thus lighten their burden a little. But the Prophet (peace and blessings be upon him) refused to give them a servant, … the whole story is mentioned … . Then the Noble Prophet (peace and blessings be upon him) said to both of them: Shall I not inform you of something better than what you have asked for? They said: Yes, indeed. The Prophet (peace and blessings be upon him) said: There are some words which Jibreel (peace be upon him) taught me. Then the Prophet (peace and blessings be upon him) said: After every prayer, say Subhan Allah ten times, Alhamdulillah ten times, and Allahu Akbar ten times. Then when you go to your bed, say Subhan Allah thirty-three times, Alhamdulillah thirty-three times, and Allahu Akbar thirty-four times. Sayyiduna Ali (may Allah be pleased with him) said: By Allah, since the Messenger of Allah (peace and blessings be upon him) taught me these words, I have never abandoned them. Ibn Kawa said: Not even on the night of Siffin? He said: O people of Iraq! May Allah destroy you, yes, yes, not even on the night of Siffin did I abandon them.
