Anas said, "The Prophet, may Allah bless him and grant him peace, used to come to us, the people of his house. One day he came to us and made supplication for us. Umm Sulaym said, 'Won't you make supplication for your little servant?' He said, 'O Allah, give him a lot of wealth and children. Make him live long and forgive him.'

حَدَّثَنَا عَارِمٌ، قَالَ: حَدَّثَنَا سَعِيدُ بْنُ زَيْدٍ، عَنْ سِنَانٍ، قَالَ: حَدَّثَنَا أَنَسٌ قَالَ: كَانَ النَّبِيُّ صلى الله عليه وسلم يَدْخُلُ عَلَيْنَا، أَهْلَ الْبَيْتِ، فَدَخَلَ يَوْمًا فَدَعَا لَنَا، فَقَالَتْ أُمُّ سُلَيْمٍ خُوَيْدِمُكَ أَلاَ تَدْعُو لَهُ؟ قَالَ: اللَّهُمَّ، أَكْثِرْ مَالَهُ وَوَلَدَهُ، وَأَطِلْ حَيَاتَهُ، وَاغْفِرْ لَهُ.
