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

(171) Obey Allah, and obey the Messenger (Muhammad صلى الله عليه وسلم); but if you turn away, then the duty of Our Messenger is only to convey (the Message) clearly.

(172) And those of your women as have passed the age of monthly courses, for them the 'Iddah (prescribed period), if you have doubt (about their periods), is three months; and for those who have no courses [(i.e. they are still immature) their 'Iddah (prescribed period) is three months likewise, except in case of death] . And for those who are pregnant (whether they are divorced or their husbands are dead), their 'Iddah (prescribed period) is until they lay down their burden; and whosoever fears Allah and keeps his duty to Him, He will make his matter easy for him.

(173) Or is it that you (O Muhammad صلى الله عليه وسلم) ask them a wage, so that they are heavily burdened with debt?

(174) While He has created you in (different) stages [i.e. first Nutfah, then 'Alaqah and then Mudghah, see (V.23:13,14)].

(175) "(Mine is) but conveyance (of the truth) from Allah and His Messages (of Islamic Monotheism), and whosoever disobeys Allah and His Messenger, then Verily, for him is the Fire of Hell, he shall dwell therein forever."

(176) [He (Allah) protects them (the Messengers)], till He sees that they (the Messengers) have conveyed the Messages of their Lord (Allah). And He (Allah) surrounds all that which is with them, and He (Allah) keeps count of all things (i.e. He knows the exact number of everything).

(177) Nay, everyone of them desires that he should be given pages spread out (coming from Allah with a writing that Islam is the right religion, and Muhammad صلى الله عليه وسلم has come with the truth from Allah, the Lord of the heavens and earth).

(178) So he (the disbeliever) neither believed (in this Qur'an and in the Message of Muhammad صلى الله عليه وسلم) nor prayed!

(179) But on the contrary, he belied (this Qur'an and the Message of Muhammad صلى الله عليه وسلم) and turned away!

(180) Verily, it is We Who have sent down the Qur'an to you (O Muhammad صلى الله عليه وسلم) by stages.
