۞ Tell them, (O Prophet): “Do you indeed disbelieve in Him and assign compeers to Him Who created the earth in two days? He is the Lord of all beings of the Universe. 9 He set firm mountains on top (of the earth) and He blessed it. And in four days He ordained in it many provisions, equal to those who ask. 10 Then He willed to the heaven when it was smoke, and to it and the earth He said: 'Come willingly, or unwillingly' 'We come willingly' they answered. 11 Then He made them seven heavens in two days and revealed to each heaven its law. And We adorned the lower heaven with lamps, and firmly secured it. All this is the firm plan of the All-Mighty, the All-Knowing. 12 If they ignore (your message), tell them, "I have warned you against a destructive blast of sound like that which struck the people of `Ad and Thamud. 13 When their messengers came unto them from before them and behind them, saying: Worship none but Allah! they said: If our Lord had willed, He surely would have sent down angels (unto us), so lo! we are disbelievers in that wherewith ye have been sent. 14 Now as for [the tribe of] Ad, they walked arrogantly on earth, [offending] against all right, and saying, "Who could have a power greater than ours?" Why - were they, then, not aware that God, who created them, had a power greater than theirs? But they went on rejecting Our messages; 15 We sent upon them a violent wind during a few ill-fated days to make them suffer a disgraceful torment in this life. Their torment in the life to come will be even more disgraceful and they will not receive any help. 16 And as for Thamud, We guided them, but they preferred blindness over guidance, so the thunderbolt of humiliating punishment seized them for what they used to earn. 17 And We saved those who believed and used to fear Allah. 18
