۞ 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 For He [it is who, after creating the earth,] placed firm mountains on it, [towering] above its surface, and bestowed [so many] blessings on it, and equitably apportioned its means of subsistence to all who would seek it: [and all this He created] in four aeons. 10 Then He turned to the heavens, and it was smoke. So He said to it and the earth: "Come with willing obedience or perforce." They said: "We come willingly." 11 In two days He determined them seven heavens, and He revealed to each heaven its commands. We decorated the lowest heaven with lamps and preserve them. Such is the decree of the Almighty, the Knower. 12 Then if they Still turn away, say thou; I warn you of a calamity like the calamity of the 'Aad and Thamud. 13 Behold, the messengers came to them, from before them and behind them, (preaching): "Serve none but Allah." They said, "If our Lord had so pleased, He would certainly have sent down angels (to preach). Now we reject your mission (altogether)." 14 Then as to Ad, they were unjustly proud in the land, and they said: Who is mightier in strength than we? Did they not see that Allah Who created them was mightier than they in strength, and they denied Our communications? 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 As for Thamood, We guided them, but they preferred blindness above guidance, so the thunderbolt of the chastisement of humiliation seized them for that they were earning. 17 But We delivered those who believed and practised righteousness. 18
