The word(s) "about" appears 148 time(s) in 139 verse(s) in Quran in Muhammad Habib Shakir translation.

(51) And I do not say to you that I have the treasures of Allah and I do not know the unseen, nor do I say that I am an angel, nor do I say about those whom your eyes hold in mean estimation (that) Allah will never grant them (any) good-- Allah knows best what is in their souls-- for then most surely I should be of the unjust.

(52) And certainly We gave the book to Musa, but it was gone against; and had not a word gone forth from your Lord, the matter would surely have been decided between them; and surely they are in a disquieting doubt about it.

(53) And even if there were a Quran with which the mountains were made to pass away, or the earth were travelled over with it, or the dead were made to speak thereby; nay! the commandment is wholly Allah's, Have not yet those who believe known that if Allah please He would certainly guide all the people? And (as for) those who disbelieve, there will not cease to afflict them because of what they do a repelling calamity, or it will alight close by their abodes, until the promise of Allah comes about; surely Allah will not fail in (His) promise.

(54) Their apostles said: Is there doubt about Allah, the Maker of the heavens and the earth? He invites you to forgive you your faults and to respite you till an appointed term. They said: You are nothing but mortals like us; you wish to turn us away from what our fathers used to worship; bring us therefore some clear authority.

(55) They said: Nay, we have come to you with that about which they disputed.

(56) So that He might make manifest to them that about which they differ, and that those who disbelieve might know that they were liars.

(57) And they set apart for what they do not know a portion of what We have given them. By Allah, you shall most certainly be questioned about that which you forged.

(58) And We have not revealed to you the Book except that you may make clear to them that about which they differ, and (as) a guidance and a mercy for a people who believe.

(59) And be not like her who unravels her yarn, disintegrating it into pieces after she has spun it strongly. You make your oaths to be means of deceit between you because (one) nation is more numerous than (another) nation. Allah only tries you by this; and He will most certainly make clear to you on the resurrection day that about which you differed.

(60) The Sabbath was ordained only for those who differed about it, and most surely your Lord will judge between them on the resurrection day concerning that about which they differed.
