Mujahid said concerning this verse: "And let not those among you who are endowed with grace and means swear": Sayyiduna Abu Bakr (may Allah be pleased with him) had sworn that he would not benefit an orphan who was raised under his guardianship. Abd al-Malik said: He was Mistah bin Uthathah bin Abbad bin al-Muttalib, who had spread that talk. When this verse was revealed: "Do you not love that Allah should forgive you?" [Surah al-Nur: 22], Sayyiduna Abu Bakr (may Allah be pleased with him) said: Yes indeed, I love that Allah should forgive me, and I will be even better to the orphans than I was before.
