Qur'an surah Hud 11:88: He said: "O my people! Tell me, if I have a clear evidence from my Lord, and He has given me a good sustenance from Himself (shall I corrupt it by mixing it with the unlawfully earned money). I wish not, in contradiction to you, to do that which I forbid you. I only desire reform so far as I am able, to the best of my power. And my guidance cannot come except from Allah, in Him I trust and unto Him I repent.
