"Remember when your Lord said to you, 'If you give thanks, I shall give you greater (favors), but if you deny the Truth, know that My retribution is severe ". 7 And Moses said: Though ye and all who are in the earth prove thankless, lo! Allah verily is Absolute, Owner of Praise. 8 Have you (believers) ever heard the news about those who lived before you, like the people of Noah, Ad, Thamud, and those who lived after them? No one knows about them except God. Messengers were sent to them with miracles, but they put their hands to their mouths and said, "We do not believe in whatever you preach and we are also doubtful and uncertain about that to which you invite 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 apostles answered them: "True, we are nothing but mortal men like yourselves: but God bestows His favour upon whomever He wills of His servants. Withal, it is not within our power to bring you a proof [of our mission,] unless it be by God's leave - and [so] it is in God that all believers must place 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
