(281) He rules (all) affairs from the heavens to the earth: in the end will (all affairs) go up to Him, on a day, the space whereof will be (as) a thousand years of your reckoning.

(283) Verily thy Lord will judge between them on the day of Judgment, in the matters wherein they differ (among themselves)

(284) Say: "On the day of Decision, no profit will it be to Unbelievers if they (then) believe! nor will they be granted a respite."

(285) Ye have indeed in the Messenger of Allah a beautiful pattern (of conduct) for any one whose hope is in Allah and the Final day, and who engages much in the Praise of Allah.

(289) "No intercession can avail in His Presence, except for those for whom He has granted permission. So far (is this the case) that, when terror is removed from their hearts (at the day of Judgment, then) will they say, 'what is it that your Lord commanded?' they will say, 'That which is true and just; and He is the Most High Most Great'."

(290) Say: "The appointment to you is for a day, which ye cannot put back for an hour nor put forward."
