And remember! your Lord caused to be declared (publicly): "If ye are grateful, I will add more (favours) unto you; But if ye show ingratitude, truly My punishment is terrible indeed." 7 And Musa (Moses) said: "If you disbelieve, you and all on earth together, then verily! Allah is Rich (Free of all wants), Owner of all Praise." 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 about God, the Originator of the heavens and earth? He calls you to Him in order to forgive you some of your offences and to reprieve you for a specific period." They said, "You are only human beings like ourselves! You want to divert us from what our forefathers have been worshipping, so bring us some clear authority." 10 Their Messengers said to them: "We are no more than human beings like you, but Allah bestows His Grace to whom He wills of His slaves. It is not ours to bring you an authority (proof) except by the Permission of Allah. And in Allah (Alone) let the 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
