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."
