Umm Sulaym said, "Messenger of Allah, your servant Anas. Pray to Allah for him."He said, "O Allah, increase his wealth and children, and bless him in what You have given him."
عن أم سليم أنها قالت: يا رسول الله، خادمك أنس، ادع الله له، فقال: اللهم أكثر ماله وولده وبارك له فيما أعطيته.
Bukhari narrated it in the Book of Supplications (6378, 6379) and Muslim in the Book of the Virtues of the Companions (2480), both of them from Muhammad bin Bashshar, who said, Ghundar narrated to us, who said, Shubah narrated to us, who said, I heard Qatada, from Anas, from Umm Salim, and he mentioned it. This is the wording of Muslim, and the wording of Bukhari is similar to it.
