The word(s) "age" appears 212 time(s) in 191 verse(s) in Quran in Mohsin Khan translation.

(151) Say (O Muhammad صلى الله عليه وسلم): "No wage do I ask of you for this (the Qur'an), nor am I one of the Mutakallifun (those who pretend and fabricate things which do not exist).

(152) It is He, Who has created you (Adam) from dust, then from a Nutfah [mixed semen drops of male and female sexual discharge (i.e. Adam's offspring)] then from a clot (a piece of coagulated blood), then brings you forth as an infant, then (makes you grow) to reach the age of full strength, and afterwards to be old (men and women)- though some among you die before,- and that you reach an appointed term in order that you may understand.

(153) And if We had sent this as a Qur'an in a foreign language (other than Arabic), they would have said: "Why are not its verses explained in detail (in our language)? What! (A Book) not in Arabic and (the Messenger) an Arab?" Say: "It is for those who believe, a guide and a healing. And as for those who disbelieve, there is heaviness (deafness) in their ears, and it (the Qur'an) is blindness for them. They are those who are called from a place far away (so they neither listen nor understand)."

(154) So unto this (religion of Islam alone and this Qur'an) then invite (people) (O Muhammad صلى الله عليه و سلم), and stand firm [on Islamic Monotheism by performing all that is ordained by Allah (good deeds), and by abstaining from all that is forbidden by Allah (sins and evil deeds)], as you are commanded, and follow not their desires but say: "I believe in whatsoever Allah has sent down of the Book [all the holy Books, - this Qur'an and the Books of the old from the Taurat (Torah), or the Injeel (Gospel) or the Pages of Ibrahim (Abraham)] and I am commanded to do justice among you. Allah is our Lord and your Lord. For us our deeds and for you your deeds. There is no dispute between us and you. Allah will assemble us (all), and to Him is the final return."

(155) But if they turn away (O Muhammad صلى الله عليه و سلم from the Islamic Monotheism, which you have brought to them). We have not sent you (O Muhammad صلى الله عليه و سلم) as a Hafiz (watcher, protector) over them (i.e. to take care of their deeds and to recompense them). Your duty is to convey (the Message). And verily, when We cause man to taste of Mercy from Us, he rejoices thereat; but when some ill befalls them because of the deeds which their hands have sent forth, then verily, man (becomes) ingrate!

(156) And before this was the Scripture of Musa (Moses) as a guide and a mercy. And this is a confirming Book (the Qur'an) in the Arabic language, to warn those who do wrong, and as glad tidings to the Muhsinun (good-doers. See the footnote of V.9:120).

(157) Therefore be patient (O Muhammad صلى الله عليه وسلم) as did the Messengers of strong will and be in no haste about them (disbelievers). On the Day when they will see that (torment) with which they are promised (i.e. threatened, it will be) as if they had not stayed more than an hour in a single day. (O mankind! this Qur'an is sufficient as) a clear Message (or proclamation to save yourself from destruction). But shall any be destroyed except the people who are Al-Fasiqun (the rebellious against Allah's Command, the disobedient to Allah)?

(158) Those who disbelieve (in the Oneness of Allah, and in the Message of Prophet Muhammad صلى الله عليه وسلم), and hinder (men) from the Path of Allah (Islamic Monotheism), He will render their deeds vain.

(159) Verily, those who have turned back (have apostatised) as disbelievers after the guidance has been manifested to them - Shaitan (Satan) has beautified for them (their false hopes), and (Allah) prolonged their term (age).

(160) The life of this world is but play and pastime; but if you believe (in the Oneness of Allah - Islamic Monotheism), and fear Allah, and avoid evil, He will grant you your wages, and will not ask you your wealth.
