The Book of Zakat (Kitab Al-Zakat)
Muslim :: Book 5 : Hadith 2298
Miswar b. Makhrama reported that the Messenger of Allah (may peace be upon him) distributed some cloaks but did not bestow one upon Makhrama. Upon this Makhrama said: 0 my son, come along with me to the Messenger of Allah (may peace be upon him). So I went with him. He said: Enter the house and call him (to come out) for me. So I called him and he (the Holy Prophet) came out, and there was a cloak (from those already distributed) on him. He (the Holy Prophet) said: I had kept it for you. He (Makhrama), looked at it and was pleased.
