And [remember the time] when your Sustainer made [this promise] known: 'If you are grateful [to Me,] I shall most certainly give you more and more; but if you are ungrateful, verily, My chastisement will be severe indeed!"' 7 And Musa said: If you are ungrateful, you and those on earth all together, most surely Allah is Self-sufficient, Praised; 8 Has not news come to you concerning those who preceded you, such as Noah's people, and the 'Ad and Thamud, as well as those who came after them? Only God knows who they were. The messengers came to them with clear signs, but they put their hands to their mouths saying, "We deny the message you have been sent with. We have grave doubts about what you are inviting us to do." 9 ۞ Their Messengers said: "Can there be any doubt about Allah, the Creator of the heavens and the earth? He invites you that He may forgive you your sins and grant you respite till an appointed term." They replied: "You are only a human being like ourselves. You seek to prevent us from serving those whom our forefathers have been serving all along. If that is so, produce a clear authority for it." 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 Why should we not trust in God when He has shown us the right way? We shall exercise patience against the troubles with which you afflict us. Whoever needs a trustee should trust in God." 12
