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

(271) And those who disbelieved say: "Why is not a sign sent down to him (Muhammad صلى الله عليه و سلم) from his Lord?" Say: "Verily, Allah sends astray whom He wills and guides unto Himself those who turn to Him in repentance."

(272) Thus have We sent you (O Muhammad صلى الله عليه و سلم) to a community before whom other communities have passed away, in order that you might recite unto them what We have revealed to you, while they disbelieve in the Most Gracious (Allah) Say: "He is my Lord! La ilaha illa Huwa (none has the right to be worshipped but He)! In Him is my trust, and to Him will be my return with repentance."

(273) And indeed (many) Messengers were mocked at before you (O Muhammad صلى الله عليه و سلم), but I granted respite to those who disbelieved, and finally I punished them. Then how (terrible) was My punishment!

(274) Those to whom We have given the Book (such as 'Abdullah bin Salam and other Jews who embraced Islam), rejoice at what has been revealed unto you (i.e. the Qur'an), but there are among the Confederates (from the Jews and pagans) those who reject a part thereof. Say (O Muhammad صلى الله عليه و سلم): "I am commanded only to worship Allah (Alone) and not to join partners with Him. To Him (Alone) I call and to Him is my return."

(275) And thus have We sent it (the Qur'an) down to be a judgement of authority in Arabic. Were you (O Muhammad صلى الله عليه و سلم) to follow their (vain) desires after the knowledge which has come to you, then you will not have any Wali (protector) or Waq (defender) against Allah.

(276) And indeed We sent Messengers before you (O Muhammad صلى الله عليه و سلم) and made for them wives and offspring. And it was not for a Messenger to bring a sign except by Allah's Leave. (For) every matter there is a Decree (from Allah). [Tafsir Al-Tabari]

(277) Whether We show you (O Muhammad صلى الله عليه و سلم) part of what We have promised them or cause you to die, your duty is only to convey (the Message) and on Us is the reckoning.

(278) And those who disbelieved, say: "You (O Muhammad صلى الله عليه و سلم) are not a Messenger." Say: "Sufficient as a witness between me and you is Allah and those too who have knowledge of the Scripture (such as 'Abdullah bin Salam and other Jews and Christians who embraced Islam)."

(279) Alif-Lam-Ra. [These letters are one of the miracles of the Qur'an, and none but Allah (Alone) knows their meanings]. (This is) a Book which We have revealed unto you (O Muhammad صلى الله عليه و سلم) in order that you might lead mankind out of darkness (of disbelief and polytheism) into light (of belief in the Oneness of Allah and Islamic Monotheism) by their Lord's Leave to the Path of the All-Mighty, the Owner of all Praise.

(280) Have you not seen those who have changed the Blessings of Allah into disbelief (by denying Prophet Muhammad صلى الله عليه و سلم and his Message of Islam), and caused their people to dwell in the house of destruction?
