The Book of Zakat (Kitab Al-Zakat)
Muslim :: Book 5 : Hadith 2296
Anas b. Malik reported: I was walking with the Messenger of Allah (may peace be upon him) and he had put on a mantle of Najran with a thick border. A bedouin met him and pulled the mantle so violently that I saw this violent pulling leaving marks of the border of the mantle on the skin of the neck of the Messenger of Allah (may peace be upon him). And he (the bedouin) said: Muhammad, issue command that I should be given out of the wealth of Allah which is at your disposal. The Messenger of Allah (may peace be upon him) turned his attention to him and smiled, and then ordered for him a gift (provision).
