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.
