It is narrated from Sayyiduna Ali (may Allah be pleased with him) that when the Prophet (peace and blessings of Allah be upon him) married his daughter, Sayyida Fatimah (may Allah be pleased with her), to him, he sent with her as dowry a woolen garment, a leather pillow stuffed with grass, two hand mills, a water skin, and two pitchers. One day, Sayyiduna Ali (may Allah be pleased with him) said to Sayyida Fatimah (may Allah be pleased with her), "By Allah! My chest has started to ache from drawing water from the well again and again. Some captives have come to your father, so go and request him for a servant." Sayyida Fatimah (may Allah be pleased with her) said, "By Allah! My hands have developed calluses from turning the hand mill." So she went to the Prophet (peace and blessings of Allah be upon him). The Prophet (peace and blessings of Allah be upon him) asked the reason for her coming. She replied that she had come to greet him. She felt shy to present her request before the Prophet (peace and blessings of Allah be upon him) and returned. Sayyiduna Ali (may Allah be pleased with him) asked, "What happened?" She said, "I felt shy to ask him for anything, so I returned." After that, both of us went together to the Prophet (peace and blessings of Allah be upon him). Sayyiduna Ali (may Allah be pleased with him) said, "O Messenger of Allah! My chest has started to ache from drawing water from the well again and again." Sayyida Fatimah (may Allah be pleased with her) said, "My hands have developed calluses from turning the hand mill. Some captives have come to you, so please grant us one of them as a servant." Upon hearing this, the Prophet (peace and blessings of Allah be upon him) said, "By Allah! I cannot give you a servant while leaving the people of Suffa, whose stomachs are stuck to their backs and I have nothing to spend on them. Rather, I will sell them and spend their price on the people of Suffa." So both of them returned. At night, the Prophet (peace and blessings of Allah be upon him) came to their house. The sheet they had was so small that if they covered their heads, their feet would be uncovered, and if they covered their feet, their heads would be uncovered. When the Prophet (peace and blessings of Allah be upon him) saw them, both of them tried to get up, but the Prophet (peace and blessings of Allah be upon him) stopped them and said, "After every prayer, say Subhan Allah, Alhamdulillah, and Allahu Akbar ten times each, and when you go to bed, say Subhan Allah thirty-three times, Alhamdulillah thirty-three times, and Allahu Akbar thirty-four times. (All your fatigue and illness will go away)." Sayyiduna Ali (may Allah be pleased with him) says, "By Allah! Since the Prophet (peace and blessings of Allah be upon him) taught me these words, I have never abandoned them." Ibn Kawwa said, "Not even on the day of Siffin?" He replied, "O people of Iraq! May Allah understand you. No, not even on the day of Siffin."
