THEY WILL ASK thee [O Prophet] about the Last Hour: "When will it come to pass?" Say: "Verily, knowledge thereof rests with my Sustainer alone. None but He will reveal it in its time. Heavily will it weigh on the heavens and the earth; [and] it will not fall upon you otherwise than of a sudden." They will ask thee - as if thou couldst gain insight into this [mystery] by dint of persistent inquiry!* Say: "Knowledge thereof rests with my Sustainer alone; but [of this] most people are unaware."
So he said [unto his followers]: "Embark in this [ship]! In the name of God be its run and its riding at anchor! Behold, my. Sustainer is indeed much-forgiving, a dispenser of grace!"

Nay, most of those [who think so] do not know [what they are saying]!
He [it is who] has created the skies without any supports that you could see,* and has placed firm mountains upon the earth, lest it sway with you,* and has caused all manner of living creatures to multiply thereon. And We* send down water from the skies, and thus We cause every noble kind [of life] to grow on earth.*
they made for him whatever he wished of sanctuaries, and statues, and basins as [large as] great watering - troughs, and cauldrons firmly anchored.* [And We said:] “Labour, O David's people, in gratitude [towards Me]* and [remember that] few are the truly grateful [even] among My servants!"*
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.*
And the earth - We have spread it wide, and set upon it mountains firm, and caused it to bring forth plants of all beauteous kinds,
and have We not set on it proud, firm mountains, and given you sweet water to drink?*
