Anas reported that Umm Sulaim said (to the Holy Prophet) Allah's Messenger, here is your servant Anas, invoke blessings of Allah upon him. Thereupon he (the Holy Prophet) said: O Allah, make an increase in his wealth, and progeny, and confer blessings upon him in everything Thou hast bestowed upon him.

حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، سَمِعْتُ
قَتَادَةَ، يُحَدِّثُ عَنْ أَنَسٍ، عَنْ أُمِّ سُلَيْمٍ، أَنَّهَا قَالَتْ يَا رَسُولَ اللَّهِ خَادِمُكَ أَنَسٌ ادْعُ اللَّهَ لَهُ
فَقَالَ
" اللَّهُمَّ أَكْثِرْ مَالَهُ وَوَلَدَهُ وَبَارِكْ لَهُ فِيمَا أَعْطَيْتَهُ " .
