Anas bin Malik reported,

The Prophet ﷺ visited Umm Sulaym, and she brought him dates and clarified butter.He said, "Put your clarified butter back in its skin and your dates back in their container. I am fasting."Then he stood in a corner of the house and prayed a voluntary prayer, after which he supplicated for Umm Sulaym and her household.Umm Sulaym said, "Messenger of Allah, I have one small request."He asked, "What is it?"She replied, "Your servant Anas."He left out no good of this world or the next without asking it for him, saying, "Allah, grant him wealth and children, and bless him in them."Anas said, I am among the wealthiest of the Ansar, and my daughter Umayna told me that by the time Hajjaj arrived in Basra, more than one hundred and twenty of my direct descendants had already been buried.

Sahih

عن أنس بن مالك قال

دخل النبي ﷺ على أم سليم، فأتته بتمر وسمن. قال: أعيدوا سمنكم في سقائه وتمركم في وعائه، إني صائم، ثم قام إلى ناحية من البيت فصلي غير المكتوبة، فدعا لأم سليم وأهل بيتها. فقالت أم سليم: يا رسول الله، إن لي خويصة، قال: ما هي؟ قالت: خادمك أنس. فما ترك خير آخرة ولا دنيا إلا دعا به: اللهم ارزقه مالا وولدا، وبارك له. فإني لمن أكثر الأنصار مالا. وحدثتني ابنتي أمينة أنه دفن لصلبي مقدم الحجاج البصرة بضع وعشرون ومائة.
