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 Moses added: "If you should [ever] deny the truth - you and whoever else lives on earth, all of you - [know that,] verily, God is indeed self-sufficient, ever to be praised!" 8 Did not the tidings of those before you reach you? The people of Nooh, and the A’ad and the Thamud, and those after them? Only Allah knows them; their Noble Messengers came to them with clear proofs, they therefore raised their hands towards their own mouths, and said, “We disbelieve in what you have been sent with, and we are in a deeply intriguing doubt regarding the path you call us to.” 9 ۞ Their messengers said, "Can there be doubt about Allah, Creator of the heavens and earth? He invites you that He may forgive you of your sins, and He delays your death for a specified term." They said, "You are not but men like us who wish to avert us from what our fathers were worshipping. So bring us a clear authority." 10 Their messengers replied, "We are indeed mortals like yourselves. But God bestows His grace on such of His servants as He chooses. We cannot give you miracles, except by God's leave. In God let true 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
