From Sahih Muslim (Hadith 6376):
Anas reported:My mother Umm Anas came to Allah's Messenger (ﷺ). And she prepared my lower garment out of the half of her headdress and (with the other half) she covered my upper body and said: Allah's Messenger, here is my son Unais; I have brought him to you for serving you. Invoke blessings of Allah upon him. Thereupon he (the Holy Prophet) said: O Allah, make an increase in his wealth, and progeny. Anas said: By Allah, my fortune is huge and my children, and grand-children are now more than one hundred
