(98) باب الصَّدَقَةِ لاَ تَحِلُّ لِلنَّبِيِّ صلى الله عليه وسلم
Bahz bin Hakim narrated from his father that his grandfather said:
"If something was brought to him, the prophet would ask whether it was a gift or charity. If it was said that if was charity, he would not eat, and if it was said that it was a gift, he would stretch forth his hand."
