Sahih Bukhari Volume 3, Book 30, Hadith 1983

حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، قَالَ حَدَّثَنِي خَالِدٌ هُوَ ابْنُ الْحَارِثِ حَدَّثَنَا حُمَيْدٌ، عَنْ أَنَسٍ رضى الله عنه دَخَلَ النَّبِيُّ صلى الله عليه وسلم عَلَى أُمِّ سُلَيْمٍ، فَأَتَتْهُ بِتَمْرٍ وَسَمْنٍ، قَالَ ‏"‏ أَعِيدُوا سَمْنَكُمْ فِي سِقَائِهِ، وَتَمْرَكُمْ فِي وِعَائِهِ، فَإِنِّي صَائِمٌ ‏"‏‏.‏ ثُمَّ قَامَ إِلَى نَاحِيَةٍ مِنَ الْبَيْتِ، فَصَلَّى غَيْرَ الْمَكْتُوبَةِ، فَدَعَا لأُمِّ سُلَيْمٍ، وَأَهْلِ بَيْتِهَا، فَقَالَتْ أُمُّ سُلَيْمٍ يَا رَسُولَ اللَّهِ، إِنَّ لِي خُوَيْصَةً، قَالَ ‏"‏ مَا هِيَ ‏"‏‏.‏ قَالَتْ خَادِمُكَ أَنَسٌ‏.‏ فَمَا تَرَكَ خَيْرَ آخِرَةٍ وَلاَ دُنْيَا إِلاَّ دَعَا لِي بِهِ قَالَ ‏"‏ اللَّهُمَّ ارْزُقْهُ مَالاً وَوَلَدًا وَبَارِكْ لَهُ ‏"‏‏.‏ فَإِنِّي لَمِنْ أَكْثَرِ الأَنْصَارِ مَالاً‏.‏ وَحَدَّثَتْنِي ابْنَتِي أُمَيْنَةُ أَنَّهُ دُفِنَ لِصُلْبِي مَقْدَمَ حَجَّاجٍ الْبَصْرَةَ بِضْعٌ وَعِشْرُونَ وَمِائَةٌ‏ وَ قَالَ ابْنُ أَبِي مَرْيَمَ، أَخْبَرَنَا يَحْيَى، قَالَ حَدَّثَنِي حُمَيْدٌ، سَمِعَ أَنَسًا رضى الله عنه عَنِ النَّبِيِّ صلى الله عليه وسلم‏

Narrated By Anas : The Prophet paid a visit to Um-Sulaim and she placed before him dates and ghee. The Prophet said, "Replace the ghee and dates in their respective containers for I am fasting." Then he stood somewhere in her house and offered an optional prayer and then he invoked good on Um-Sulaim and her family. Then Um-Sulaim said, "O Allah's Apostle! I have a special request (today)." He said, "What is it?" She replied, "(Please invoke for) your servant Anas." So Allah's Apostle did not leave anything good in the world or the Hereafter which he did not invoke (Allah to bestow) on me and said, "O Allah! Give him (i.e. Anas) property and children and bless him." Thus I am one of the richest among the Ansar and my daughter Umaina told me that when A-Hajjaj came to Basra, more than 120 of my offspring had been buried.
