"When something was brought to him, the Messenger of Allah would ask: 'Is this charity or a gift?' If they said: 'Charity.' He would not eat it, and if they said, 'A gift' he would eat it."
Jami` at-Tirmidhi Book 7, Hadith 40
← Previous Hadith "During the time of the Messenger of Allah, a man suffered a loss on fruits that he had sold, resulting in more debt. The Messenger of Allah said: 'Give him charity.' So the people gave him charity but it did not cover his debt. So the Messenger of Allah said to his debtors: 'Take what you have and there is nothing for you but that.'"

Jami` at-Tirmidhi Book 7, Hadith 39 Next Hadith → the Messenger of Allah sent a man from Banu Makhzun to collect charity, so he said to Abu Rafi: "Accompany me so that perhaps you may have some of it." So he said: "Not until I ask the Messenger of Allah." So he went to the Prophet to ask him, and he said: "Charity is not lawful for us, and to be the Mawda of a people to be the same as them."
