Remember also the time when your Lord declared, 'If you are grateful, I will surely bestow more favours on you; but if you are ungrateful, then know that My punishment is severe indeed.'" 7 Moses said: "Were you to disbelieve - you and all those who live on earth - Allah is still Self-Sufficient, Innately Praiseworthy." 8 Hath not the history of those before you reached you: the folk of Noah, and (the tribes of) A'ad and Thamud, and those after them? None save Allah knoweth them. Their messengers came unto them with clear proofs, but they thrust their hands into their mouths, and said: Lo! we disbelieve in that wherewith ye have been sent, and lo! we are in grave doubt concerning that to which ye call us. 9 ۞ Their Messengers said, 'Is there any doubt regarding God, the Originator of the heavens and the earth, who calls you so that He may forgive you your sins, and defer you to a term stated?' They said, 'You are nothing but mortals, like us; you desire to bar us from that our fathers served; then bring us a manifest authority.' 10 Their messengers said unto them: We are but mortals like you, but Allah giveth grace unto whom He will of His slaves. It is not ours to bring you a warrant unless by the permission of Allah. In Allah let believers put their trust! 11 And what reason have we that we should not rely on Allah? And He has indeed guided us in our ways; and certainly we would bear with patience your persecution of us; and on Allah should the reliant rely. 12
