It is narrated from Sayyiduna Ka‘b bin Malik (may Allah be pleased with him) that he said: O Messenger of Allah! Indeed, the requirement for the acceptance of my repentance is that I give up all my wealth and give it in charity for Allah and His Messenger. The Prophet (peace and blessings be upon him) said: Keep some of your wealth with you; it will be better for you. I said: Then I will keep that portion with me which I received in Khaybar.

It is narrated from Sayyiduna Abu Lubabah bin Abd al-Mundhir (may Allah be pleased with him) that when Allah Almighty accepted his repentance, he said: O Messenger of Allah! Surely, the requirement of my repentance being accepted is that I leave the area of my people and stay with you, and that I give away my wealth in charity for Allah Almighty and His Messenger, thus removing myself from it. But the Prophet (peace and blessings be upon him and his family) said: Giving charity of one third of your wealth will suffice for you.
