Sayyiduna Abu Lubabah (may Allah be pleased with him) said: O Messenger of Allah! Part of my repentance is that I leave the house of my people where I committed the sin, and that I give up my wealth as charity for Allah and His Messenger. The Messenger of Allah (peace and blessings be upon him) said: "A third of your wealth is sufficient for you."
