"The Messenger of Allah said: 'Give charity.' A man said: 'O Messenger of Allah, I have a Dinar.' He said: 'Spend it on yourself.' He said: 'I have another.' He said: 'Spend it on your wife.' He said: 'I have another.' He said: 'Spend it on your son.' He said: 'I have another.' He said: 'Spend it on your servant.' He said: 'I have another.' He said: 'You know best (what to do with it)."'
Sunan an-Nasa'i Book 23, Hadith 101
← Previous Hadith "The best of charity is that which is given when you are self-sufficient, and the upper hand is better than the lower hand, and start with those for whom you are responsible."

Sunan an-Nasa'i Book 23, Hadith 100 Next Hadith → a man entered the Msjid on a Friday when the Messenger of Allah was delivering the Khutbah, and he said: "Pray two Rak'ahs." Then he came on the following Friday, when the Prophet was delivering the Khutbah and he said: "Pray two Rak'ahs." Then he came on the third Friday, when the Prophet was delivering Khutbah and he said: "Pray two Rak'ahs." Then he said: "Give in charity." So they gave in charity, and he gave him (that man) two garments. Then he said: "Give in charity" and (that man) threw one of his two garments. The Messenger of Allah said: "Have you not seen this man? He entered the Masjid in scruffy clothes and I hoped that you would notice him, and give charity to him, but you did not do that, So I said, 'Give in charity.' You gave in charity, and I gave him two garments, then I said; 'Give in charity' and he threw one of his two garments. Take your garment." And he rebuked him.
