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

(451) Thus does Allah seal up the hearts of those who know not [the proofs and evidence of the Oneness of Allah i.e. those who try not to understand true facts that which you (Muhammad صلى الله عليه وسلم) have brought to them].

(452) So be patient (O Muhammad صلى الله عليه وسلم). Verily, the Promise of Allah is true; and let not those who have no certainty of faith, discourage you from conveying Allah's Message (which you are obliged to convey).

(453) And whosoever submits his face (himself) to Allah, while he is a Muhsin (good-doer i.e. performs good deeds totally for Allah's sake without any show off or to gain praise or fame and does them in accordance with the Sunnah of Allah's Messenger Muhammad صلى الله عليه وسلم), then he has grasped the most trustworthy handhold [La ilaha illallah (none has the right to be worshipped but Allah)]. And to Allah return all matters for decision.

(454) And whoever disbelieves, let not his disbelief grieve you (O Muhammad صلى الله عليه وسلم). To Us is their return, and We shall inform them what they have done. Verily, Allah is the All-Knower of what is in the breasts (of men).

(455) And if you (O Muhammad صلى الله عليه وسلم) ask them: "Who has created the heavens and the earth," they will certainly say: "Allah." Say: "All the praises and thanks be to Allah!" But most of them know not.

(456) See you not (O Muhammad صلى الله عليه وسلم) that Allah merges the night into the day (i.e. the decrease in the hours of the night are added to the hours of the day), and merges the day into the night (i.e. the decrease in the hours of day are added to the hours of night), and has subjected the sun and the moon, each running its course for a term appointed; and that Allah is All-Aware of what you do.

(457) Or say they: "He (Muhammad صلى الله عليه وسلم) has fabricated it?" Nay, it is the truth from your Lord, so that you may warn a people to whom no warner has come before you (O Muhammad صلى الله عليه وسلم): in order that they may be guided.

(458) So turn aside from them (O Muhammad صلى الله عليه وسلم) and await: verily, they (too) are awaiting.

(459) O Prophet (Muhammad صلى الله عليه وسلم)! Keep your duty to Allah, and obey not the disbelievers and the hypocrites (i.e., do not follow their advice). Verily, Allah is Ever All-Knower, All-Wise.

(460) And (remember) when We took from the Prophets their covenant, and from you (O Muhammad صلى الله عليه وسلم), and from Nuh (Noah), Ibrahim (Abraham), Musa (Moses), and 'Îsa (Jesus) son of Maryam (Mary). We took from them a strong covenant.
