Kulaini has narrated through authentic chains from Imam Ja’far Sadiq (a.s.) that a group of Yemenite nobles came to the Messenger of Allah (S) and among them was a person whose speech was most eloquent and he began to dispute with the Prophet. The Prophet became angry, his eyes and face became red. So he looked down for some time. Jibraeel descended from the heavens and said: “After greetings Your Lord says that this man is generous and brave, he feeds the poor.”
The Prophet’s anger was immediately dispelled and then he said: “If Jibraeel had not informed me that you are generous and brave and that you feed the poor, so I would have given you such a punishment that it would have served as a lesson for your companions who are coming behind you. The man asked: “Does your Lord like generosity?” the Holy Prophet (S) replied in the positive. He said: “I testify to the Oneness of Allah and your messengership, and I swear by the same God who sent you with truth that I never turned back anyone without giving something from my property.
