The word(s) "about" appears 182 time(s) in 175 verse(s) in Quran in Mohsin Khan translation.

(1) And when they (Jews) meet those who believe (Muslims), they say, "We believe", but when they meet one another in private, they say, "Shall you (Jews) tell them (Muslims) what Allah has revealed to you [Jews, about the description and the qualities of Prophet Muhammad صلى الله عليه وسلم, that which are written in the Taurat (Torah)] , that they (Muslims) may argue with you (Jews) about it before your Lord?" Have you (Jews) then no understanding?

(2) And (remember) when We took a covenant from the Children of Israel, (saying): Worship none but Allah (Alone) and be dutiful and good to parents, and to kindred, and to orphans and Al-Masakin (the poor), and speak good to people [i.e. enjoin righteousness and forbid evil, and say the truth about Muhammad صلى الله عليه وسلم], and perform As-Salat (Iqamat-as-Salat), and give Zakat. Then you slid back, except a few of you, while you are backsliders. (Tafsir Al-Qurtubi).

(3) And indeed We have sent down to you manifest Ayat (these Verses of the Qur'an which inform in detail about the news of the Jews and their secret intentions, etc.), and none disbelieve in them but Fasiqun (those who rebel against Allah's Command).

(4) The Jews said that the Christians follow nothing (i.e. are not on the right religion); and the Christians said that the Jews follow nothing (i.e. are not on the right religion); though they both recite the Scripture. Like unto their word, said (the pagans) who know not. Allah will judge between them on the Day of Resurrection about that wherein they have been differing.

(5) Verily, We have sent you (O Muhammad صلى الله عليه وسلم) with the truth (Islam), a bringer of glad tidings (for those who believe in what you brought, that they will enter Paradise) and a warner (for those who disbelieve in what you brought, that they will enter the Hell-fire). And you will not be asked about the dwellers of the blazing Fire.

(6) Say (O Muhammad صلى الله عليه وسلم to the Jews and Christians), "Dispute you with us about Allah while He is our Lord and your Lord? And we are to be rewarded for our deeds and you for your deeds. And we are sincere to Him [in worship and obedience (i.e. we worship Him Alone and none else, and we obey His Orders)]."

(7) They ask you (O Muhammad صلى الله عليه وسلم) about the new moons. Say: These are signs to mark fixed periods of time for mankind and for the pilgrimage. It is not Al-Birr (piety, righteousness) that you enter the houses from the back but Al-Birr (is the quality of the one) who fears Allah. So enter houses through their proper doors, and fear Allah that you may be successful.

(8) Have you not thought about the group of the Children of Israel after (the time of) Musa (Moses)? When they said to a Prophet of theirs, "Appoint for us a king and we will fight in Allah's Way." He said, "Would you then refrain from fighting, if fighting was prescribed for you?" They said, "Why should we not fight in Allah's Way while we have been driven out of our homes and our children (families have been taken as captives)?" But when fighting was ordered for them, they turned away, all except a few of them. And Allah is All-Aware of the Zalimun (polytheists and wrong-doers).

(9) Have you not looked at him who disputed with Ibrahim (Abraham) about his Lord (Allah), because Allah had given him the kingdom? When Ibrahim (Abraham) said (to him): "My Lord (Allah) is He Who gives life and causes death." He said, "I give life and cause death." Ibrahim (Abraham) said, "Verily! Allah brings the sun from the east; then bring it you from the west." So the disbeliever was utterly defeated. And Allah guides not the people, who are Zalimun (wrong-doers).

(10) (Charity is) for Fuqara (the poor), who in Allah's Cause are restricted (from travel), and cannot move about in the land (for trade or work). The one who knows them not, thinks that they are rich because of their modesty. You may know them by their mark, they do not beg of people at all. And whatever you spend in good, surely, Allah knows it well.
