Ali bin Abu Talib reported,

When the Messenger of Allah ﷺ married Fatimah to Ali, he sent with him a velvet cloth, a leather cushion stuffed with palm fiber, two millstones, a waterskin, and two jars.One day Ali said to Fatimah, "By Allah, I have drawn water until my chest aches. Allah has now brought your father captives, so go and ask him for a servant."Fatimah replied, "And by Allah, I have ground grain until my hands are blistered."So she went to the Prophet ﷺ, and he asked, "What brings you, my little daughter?"She said, "I came to greet you with peace." She felt too shy to ask him, so she returned.Ali asked her, "What did you do?"She said, "I was too shy to ask him."So we both went to him together, and Ali said, "Messenger of Allah, by Allah, I have drawn water until my chest aches."Fatimah said, "I have ground grain until my hands are blistered. Allah has brought you captives and abundance, so let us have some."The Messenger of Allah ﷺ replied, "By Allah, I will not give to you both and leave the people of the Suffah with their bellies folded in hunger, having nothing to spend on them. Rather, I will sell the captives and spend their price on them."So they returned. Then the Prophet ﷺ came to them after they had entered beneath their blanket. When they covered their heads, their feet were exposed, and when they covered their feet, their heads were exposed. They sprang up, but he said, "Stay where you are."Then he said, "Shall I not tell you of something better than what you asked me for?"They said, "Yes indeed."He said, "Words that Jibreel taught me. Glorify Allah ten times after every prayer, praise Him ten times, and magnify Him ten times. And when you retire to your bed, glorify Him thirty-three times, praise Him thirty-three times, and magnify Him thirty-four times."Ali said, "By Allah, I have not abandoned them since the Messenger of Allah ﷺ taught them to me."Ibn al-Kawwa asked him, "Not even on the night of Siffin?"He replied, "May Allah fight you, people of Iraq. Yes, not even on the night of Siffin."

عن علي بن أبي طالب

أن رسول الله ﷺ لما زوجه فاطمة بعث معه بخميلة ووسادة من أدم حشوها ليف، ورحيين وسقاء وجرتين، فقال علي لفاطمة ذات يوم: والله لقد سنوت حتى قد اشتكيت صدري، قال: وقد جاء الله أباك بسبي، فاذهبي فاستخدميه، فقالت: وأنا والله قد طحنت حتى مجلت يداي فأتت النبي ﷺ، فقال: ماجاء بك أي بنية؟ قالت: جئت لأسلم عليك، واستحيت أن تسأله ورجعت، فقال: ما فعلت؟ قالت: استحييت أن أسأله، فأتيناه جميعا، فقال علي: يا رسول الله، والله لقد سنوت حتى اشتكيت صدري، وقالت فاطمة: قد طحنت حتى مجلت يداي، وقد جاءك الله بسبي وسعة فأخذ منا، فقال رسول الله ﷺ: والله لا أعطيكما وأدع أهل الصفة تطوى بطونهم، لا أجد ما أنفق عليهم، ولكني أبيعهم وأنفق عليهم أثمانهم. فرجعا، فأتاهما النبي ﷺ و قد دخلا في قطيفتهما، إذا غطت رءوسهما تكشفت أقدامهما، وإذا غطيا أقدامهما تكشفت رءوسهما، فثارا، فقال: مكانكما. ثم قال: ألا أخبركما بخير مما سألتماني؟ قالا: بلى. فقال: كلمات علمنيهن جبريل، فقال: تسبحان في دبر كل صلاة عشرا، وتحمدان عشرا، وتكبران عشرا، وإذا أويتما إلى فراشكما فسبحا ثلاثا وثلاثين، واحمدا ثلاثا وثلاثين، وكبرا أربعا وثلاثين. قال: فو الله ما تركتهن منذ علمنيهن رسول الله ﷺ، قال: فقال له ابن الكواء: ولا ليلة صفين؟ فقال: قاتلكم الله يا أهل العراق، نعم، ولا ليلة صفين.
