Harun bin Ra'aib هارون بن رئاب · The Book of Zakah

" The poor man stands at my door, and I cannot find anything to give him. " The Messenger of Allah said to her: "If you cannot find anything to give to him except a sheep's burned foot, then give it to him."

"The Messenger of Allah said: "There are three to whom Allah, it Mighty and Sublime, with not speak on the Day of Resurrection: An old man who commits adultery, a poor man who is arrogant, and an Imam who tells lies."'

a man came to the prophet and asked him and he gave him, and when he placed his foot on the threshold the Messenger of Allah said: "If you knew how bad begging is, no one would go to anyone else and ask him for anything."
