[Machine] The Prophet's ﷺ wife said: "Abu Bakr used to financially support Mistah bin Uthatha. But when he spoke ill of Aisha, Abu Bakr swore by Allah that he would never financially support him again. Then, when Allah revealed the verse {And let not those of virtue among you and wealth swear not to give [aid] to their relatives and the needy and the emigrants for the cause of Allah}, Abu Bakr said: 'Yes, by Allah, I would really like Allah to forgive me.' So Abu Bakr resumed supporting Mistah and paid the expiation for his right hand. Ash-Shafi'i may Allah have mercy on him said: 'And the saying of Allah the Exalted {And indeed, they say much that is untrue and also false} [Al-Mujadila: 2] demonstrates the obligation of expiation in it due to the clear textual evidence. And the news regarding it has already been mentioned in the Book of Az-Zahar."
