Say, O [Muhammad], "I am only a man like you to whom it has been revealed that your god is but one God; so take a straight course to Him and seek His forgiveness." And woe to those who associate others with Allah -
And He placed on the earth firmly set mountains over its surface, and He blessed it and determined therein its [creatures'] sustenance in four days without distinction - for [the information] of those who ask.
And He completed them as seven heavens within two days and inspired in each heaven its command. And We adorned the nearest heaven with lamps and as protection. That is the determination of the Exalted in Might, the Knowing.
[That occurred] when the messengers had come to them before them and after them, [saying], "Worship not except Allah ." They said, "If our Lord had willed, He would have sent down the angels, so indeed we, in that with which you have been sent, are disbelievers."
As for 'Aad, they were arrogant upon the earth without right and said, "Who is greater than us in strength?" Did they not consider that Allah who created them was greater than them in strength? But they were rejecting Our signs.
So We sent upon them a screaming wind during days of misfortune to make them taste the punishment of disgrace in the worldly life; but the punishment of the Hereafter is more disgracing, and they will not be helped.
And they will say to their skins, "Why have you testified against us?" They will say, "We were made to speak by Allah , who has made everything speak; and He created you the first time, and to Him you are returned.
And We appointed for them companions who made attractive to them what was before them and what was behind them [of sin], and the word has come into effect upon them among nations which had passed on before them of jinn and men. Indeed, they [all] were losers.
Indeed, those who have said, "Our Lord is Allah " and then remained on a right course - the angels will descend upon them, [saying], "Do not fear and do not grieve but receive good tidings of Paradise, which you were promised.
