Abdur Rahman bin 'Amr al-Awza'i عبد الرحمن بن عمرو أبو عمرو الأوزاعي · The Book of Zakah

"The Messenger of Allah mentioned the Fire, and he turned his face away (as if seeing it), and sought refuge with Allah from it." (One of the narrators) Shu'bah said: "He did that three times, then he said: 'Protect yourselves from the Fire even with half a date, and if you cannot find that, then with a good word."'

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."

"The Messenger of Allah said: 'It is not permissible to give charity to a rich man (or one who is independent of means) or to one who is strong and healthy."'
