Translation of the verse 10 from Surah Ibrahim : Number of verses 52 - - page 256 - Part 13.
Their Messengers said: "What! Can there be a doubt about Allah, the Creator of the heavens and the earth? He calls you (to Monotheism and to be obedient to Allah) that He may forgive you of your sins and give you respite for a term appointed." They said: "You are no more than human beings like us! You wish to turn us away from what our fathers used to worship. Then bring us a clear authority i.e. a clear proof of what you say)."
Their messengers said, "Can there be doubt about Allah, Creator of the heavens and earth? He invites you that He may forgive you of your sins, and He delays your death for a specified term." They said, "You are not but men like us who wish to avert us from what our fathers were worshipping. So bring us a clear authority."
(14:10) The Messengers said, "Do you have doubt about the existence of Allah. Who is the Creator of the heavens and the earth? *17 He calls you that He may forgive you your sins and give you respite till your appointed term. " *18
*17) The Messengers posed this question to those who rejected the Message in order to bring home to them the absurdity of their stand with regard to God. For though . the mushriks of every age believed in the existence of God and acknowledged that He was the Creator of the heavens and the earth, they did not accept the Message, its logical result, that He alone was entitled to their worship. That is why the Messengers. asked them, "Do you have any doubt about the existence of Allah?"
*18) In the case of individuals, the `appointed term' may be either the time of one's death or the Doomsday. As regards the `appointed term' for the rise and fall of communities, it is determined by their collective behaviour. For instance, if a capable community degenerates before the expiry of its term, the assigned period is shortened and it is deposed. On the other hand, if a degenerate community changes its ways for the better, its term is extended, So much so that it may extend even to the Doomsday. This same thing is implied in v. 11 of Ar-R'ad:"...The fact is that AIlah dces not change a people's lot unless they themselves change their own characteristics ....."
