The word(s) "amm" appears 801 time(s) in 732 verse(s) in Quran in Mohsin Khan translation.

(291) And when it is said to them: "What is it that your Lord has sent down (unto Muhammad صلى الله عليه و سلم)?" They say: "Tales of the men of old!"

(292) If you (O Muhammad صلى الله عليه و سلم) covet for their guidance, then verily Allah guides not those whom He makes to go astray (or none can guide him whom Allah sends astray). And they will have no helpers.

(293) And We sent not (as Our Messengers) before you (O Muhammad صلى الله عليه و سلم) any but men, whom We sent revelation, (to preach and invite mankind to believe in the Oneness of Allah). So ask (you, O pagans of Makkah) of those who know the Scripture [learned men of the Taurat (Torah) and the Injeel (Gospel)], if you know not.

(294) With clear signs and Books (We sent the Messengers). And We have also sent down unto you (O Muhammad صلى الله عليه و سلم) the Dhikr [reminder and the advice (i.e. the Qur'an)], that you may explain clearly to men what is sent down to them, and that they may give thought.

(295) By Allah, We indeed sent (Messengers) to the nations before you (O Muhammad صلى الله عليه و سلم), but Shaitan (Satan) made their deeds fair-seeming to them. So he (Satan) is their Wali (helper) today (i.e. in this world), and theirs will be a painful torment.

(296) And We have not sent down the Book (the Qur'an) to you (O Muhammad صلى الله عليه و سلم), except that you may explain clearly unto them those things in which they differ, and (as) a guidance and a mercy for a folk who believe.

(297) Then, if they turn away, your duty (O Muhammad صلى الله عليه و سلم) is only to convey (the Message) in a clear way.

(298) They recognise the Grace of Allah, yet they deny it (by worshipping others besides Allah) and most of them are disbelievers (deny the Prophethood of Muhammad صلى الله عليه و سلم).

(299) And (remember) the Day when We shall raise up from every nation a witness against them from amongst themselves. And We shall bring you (O Muhammad صلى الله عليه و سلم) as a witness against these. And We have sent down to you the Book (the Qur'an) as an exposition of everything, a guidance, a mercy, and glad tidings for those who have submitted themselves (to Allah as Muslims).

(300) And be not like her who undoes the thread which she has spun, after it has become strong, by taking your oaths as a means of deception among yourselves, lest a nation should be more numerous than another nation. Allah only tests you by this [i.e who obeys Allah and fulfils Allah's Covenant and who disobeys Allah and breaks Allah's Covenant]. And on the Day of Resurrection, He will certainly make clear to you that wherein you used to differ [i.e. a believer confesses and believes in the Oneness of Allah and in the Prophethood of Prophet Muhammad صلى الله عليه و سلم which the disbeliever denies and that is their difference amongst them in the life of this world] .
