Saad bin Abu Waqqas reported,

Umm Saad swore that she would never speak to him again until he renounced his religion, and that she would neither eat nor drink.She said, "You claim that Allah has charged you to care for your parents. I am your mother, and I command you to do this."Saad said, "She held out for three days, until she fainted from exhaustion. Then a son of hers named Umara got up and gave her something to drink, and she began praying against Saad. So Allah revealed this verse in the Quran, 'And We have enjoined upon man goodness toward his parents' [Ankabut 29:8], and 'But if they strive to make you associate others with Me' [Luqman 31:15], and in the same passage, 'and keep company with them in this world in a kindly manner' [Luqman 31:15]."Saad continued, "The Messenger of Allah ﷺ took a great quantity of spoils, and among them was a sword. I took it and brought it to the Messenger ﷺ and said, 'Award me this sword, for you know well what my situation is.'He said, 'Put it back where you got it from.'So I set off, but when I was about to throw it onto the pile of spoils, I reproached myself and went back to him and said, 'Give it to me.'He raised his voice and said, 'Put it back where you got it from.'Then Allah revealed, 'They ask you about the spoils' [Anfal 8:1]."Saad said, "I fell ill and sent word to the Prophet ﷺ, and he came to me. I said, 'Let me distribute my wealth however I wish.'He refused.I said, 'Then half.'He refused.I said, 'Then a third.'He said nothing, and after that a third was permitted."Saad said, "I came upon a group of the Ansar and the Emigrants, and they said, 'Come, we will feed you and give you wine to drink.' This was before wine was forbidden. So I went to them in a walled garden, and there was a roasted camel's head with them and a skin of wine. I ate and drank with them, and the Ansar and the Emigrants were mentioned in their company. I said, 'The Emigrants are better than the Ansar.'At that, one of the men took one of the jawbones of the head and struck me with it, cutting my nose. I went to the Messenger of Allah ﷺ and told him about it, and Allah revealed concerning me, meaning himself, about wine, 'Wine, gambling, idols, and divining arrows are but a defilement from the work of Satan' [Maidah 5:90]."

عن سعد بن أبي وقاص أنه نزلت فيه آيات من القرآن، قال

فحلفت أم سعد أن لا تكلمه أبدا حتى يكفر بدينه، ولا تأكل، ولا تشرب قالت: زعمت أن الله وصاك بوالديك، وأنا أمك، وأنا آمرك بهذا قال: مكثت ثلاثا حتى غشى عليها من الجهد، فقام ابن لها يقال له: عمارة فسقاها، فجعلت تدعو على سعد، فأنزل الله عز وجل في القرآن هذه الآية: {ووصينا الإنسن بوالديه حسنا} [العنكبوت: ٨] {وان جاهداك على ان تشرك بي} [القمان: ١٥] وفيها {وصاحبهما في الدنيا معروفا} [القمان: ١٥]. قال: وأصاب رسول الله ﷺ غنيمة عظيمة، فإذا فيها سيف، فأخذته فأتيت به الرسول ﷺ، فقلت: نفلني هذا السيف، فأنا من قد علمت حاله. فقال: رده من حيث أخذته. فانطلقت حتى إذا أردت أن ألقيه في القبض لامتني نفسي فرجعت إليه، فقلت: أعطنيه. قال: فشد صوته: رده من حيث أخذته. قال: فأنزل الله عز وجل: {يستلونك عن الأنفال} [الأنفال: ١]. قال: ومرضت فأرسلت إلى النبي ﷺ، فأتاني، فقلت: دعني أقسم مالي حيث شئت قال: فأبي قلت: فالنصف. قال: فأبي. قلت: فالثلث قال: فسكت فكان بعد الثلث جائزا. قال: وأتيت على نفر من الأنصار والمهاجرين، فقالوا: تعال نطعمك ونسقيك خمرا. وذلك قبل أن تحرم الخمر، قال: فأتيتهم في حش- والحش البستان- فإذا رأس جزور مشوي عندهم، وزق من خمر، قال: فأكلت و شربت معهم قال: فذكرت الأنصار والمهاجرون عندهم. فقلت: المهاجرون خير من الأنصار. قال: فأخذ رجل أحد لحيي الرأس فضربني به فجرح بأنفي فأتيت رسول الله ﷺ، فأخبرته، فأنزل الله عز وجل في- يعني نفسه- شأن الخمر: {إنما الخمر والميسر والأنصاب والأزلم رجس من عمل الشيطن} [المائدة: ٩٠].
