And he invoked blessings for me (that I should be bestowed upon) every good and this was what he (said) at the end of what be supplicated for me: O Allah, make an increase in his wealth, and progeny, and cqnfer blessings (upon him) in (each one) of them.
وَحَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا هَاشِمُ بْنُ الْقَاسِمِ، حَدَّثَنَا سُلَيْمَانُ، عَنْ ثَابِتٍ، عَنْ 
 أَنَسٍ، قَالَ دَخَلَ النَّبِيُّ صلى الله عليه وسلم عَلَيْنَا وَمَا هُوَ إِلاَّ أَنَا وَأُمِّي وَأُمُّ حَرَامٍ خَالَتِي
 فَقَالَتْ أُمِّي يَا رَسُولَ اللَّهِ خُوَيْدِمُكَ ادْعُ اللَّهَ لَهُ - قَالَ - فَدَعَا لِي بِكُلِّ خَيْرٍ وَكَانَ فِي
 آخِرِ مَا دَعَا لِي بِهِ أَنْ قَالَ ‏
"‏ اللَّهُمَّ أَكْثِرْ مَالَهُ وَوَلَدَهُ وَبَارِكْ لَهُ فِيهِ ‏"‏ ‏.‏
