(22) Recite unto them the story of Noah, when he told his people: O my people! If my sojourn (here) and my reminding you by Allah's revelations are an offence unto you, in Allah have I put my trust, so decide upon your course of action you and your partners. Let not your course of action be in doubt for you. Then have at me, give me no respite.

I desire not to do behind your backs that which I ask you not to do. I desire naught save reform so far as I am able. My welfare is only in Allah. In Him I trust and unto Him I turn (repentant).
