Al-Adab Al-Mufrad, Book 5, Hadith 88 (English) ⓘ
Anas said, "One day I visited the Prophet, may Allah bless him and grant him peace, and there was only myself, my mother and my aunt, Umm Hiram. When he came to us, he asked us, 'Shall I pray with you?' It was not the time of an obligatory prayer." One of those listening to the person relating this asked, "Where did he put in Anas in relation to him?" The reply was, "He put him to his right." The report from Anas continues, "Then he prayed with us and made supplication for us, the people of the house, that we would have the best of the blessings of this world and the Next. My mother said, 'Messenger of Allah, make supplication to Allah for your little servant,' and he asked Allah to grant me every blessing. At the end of his supplication, he said, 'O Allah, grant him a lot of money and many children and bless him!'"
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، قَالَ: حَدَّثَنَا سُلَيْمَانُ بْنُ الْمُغِيرَةِ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ قَالَ: دَخَلْتُ عَلَى النَّبِيِّ صلى الله عليه وسلم يَوْمًا، وَمَا هُوَ إِلاَّ أَنَا وَأُمِّي وَأُمُّ حَرَامٍ خَالَتِي، إِذْ دَخَلَ عَلَيْنَا فَقَالَ لَنَا: أَلاَ أُصَلِّي بِكُمْ؟ وَذَاكَ فِي غَيْرِ وَقْتِ صَلاَةٍ، فَقَالَ رَجُلٌ مِنَ الْقَوْمِ: فَأَيْنَ جَعَلَ أَنَسًا مِنْهُ؟ فَقَالَ: جَعَلَهُ عَنْ يَمِينِهِ؟ ثُمَّ صَلَّى بِنَا، ثُمَّ دَعَا لَنَا أَهْلَ الْبَيْتِ بِكُلِّ خَيْرٍ مِنْ خَيْرِ الدُّنْيَا وَالْآخِرَةِ، فَقَالَتْ أُمِّي: يَا رَسُولَ اللهِ، خُوَيْدِمُكَ، ادْعُ اللَّهَ لَهُ، فَدَعَا لِي بِكُلِّ خَيْرٍ، كَانَ فِي آخِرِ دُعَائِهِ أَنْ قَالَ: اللَّهُمَّ أَكْثِرْ مَالَهُ وَوَلَدَهُ، وَبَارِكْ لَهُ.
