The word(s) "ah" appears 5022 time(s) in 2793 verse(s) in Quran in Mohsin Khan translation.

(1641) Say: "It (this Qur'an) has been sent down by Him (Allah) (the Real Lord of the heavens and earth) Who knows the secret of the heavens and the earth. Truly, He is Oft-Forgiving, Most Merciful."

(1642) And on the Day when He will gather them together and that which they worship besides Allah [idols, angels, pious men, saints] . He will say: "Was it you who misled these My slaves or did they (themselves) stray from the (Right) Path?"

(1643) Thus they (false gods - all deities other than Allah) will belie you (polytheists) regarding what you say (that they are gods besides Allah): then you can neither avert (the punishment), nor get help. And whoever among you does wrong (i.e. sets up rivals to Allah), We shall make him taste a great torment.

(1644) On the Day they will see the angels - no glad tidings will there be for the Mujrimun (criminals, disbelievers, polytheists, sinners) that day. And they (angels) will say: "All kinds of glad tidings are forbidden to you," [none will be allowed to enter Paradise except the one who said: La ilaha illallah, "(none has the right to be worshipped but Allah) and acted practically on its legal orders and obligations. See the footnote of V.2:193)].

(1645) The sovereignty on that Day will be the true (sovereignty), belonging to the Most Gracious (Allah), and it will be a hard Day for the disbelievers (those who disbelieve in the Oneness of Allah - Islamic Monotheism).

(1646) "ah! Woe to me! Would that I had never taken so-and-so as a Khalil (an intimate friend)!

(1647) And indeed We gave Musa (Moses) the Scripture [the Taurat (Torah)], and placed his brother Harun (Aaron) with him as a helper;

(1648) And Nuh's (Noah) people, when they denied the Messengers, We drowned them, and We made them as a sign for mankind. And We have prepared a painful torment for the Zalimun (polytheists and wrong-doers).

(1649) And when they see you (O Muhammad صلى الله عليه وسلم), they treat you only in mockery (saying): "Is this the one whom Allah has sent as a Messenger?

(1650) "He would have nearly misled us from our alihah (gods), had it not been that we were patient and constant in their worship!" And they will know when they see the torment, who it is that is most astray from the (Right) Path!
