The word(s) "concerning" appears 137 time(s) in 127 verse(s) in Quran in Muhammad Pickthal translation.

(101) And We assigned them comrades (in the world), who made their present and their past fairseeming unto them. And the Word concerning nations of the jinn and humankind who passed away before them hath effect for them. Lo! they were ever losers.

(102) And We verily gave Moses the Scripture, but there hath been dispute concerning it; and but for a Word that had already gone forth from thy Lord, it would ere now have been judged between them; but lo! they are in hopeless doubt concerning it.

(103) And they were not divided until after the knowledge came unto them, through rivalry among themselves; and had it not been for a Word that had already gone forth from thy Lord for an appointed term, it surely had been judged between them. And those who were made to inherit the Scripture after them are verily in hopeless doubt concerning it.

(104) And those who argue concerning Allah after He hath been acknowledged, their argument hath no weight with their Lord, and wrath is upon them and theirs will be an awful doom.

(105) Those who believe not therein seek to hasten it, while those who believe are fearful of it and know that it is the Truth. Are not they who dispute, in doubt concerning the Hour, far astray?

(106) Or say they: He hath invented a lie concerning Allah? If Allah willed, He could have sealed thy heart (against them). And Allah will wipe out the lie and will vindicate the truth by His words. Lo! He is Aware of what is hidden in the breasts (of men).

(107) And that those who argue concerning Our revelations may know they have no refuge.

(108) And lo! verily there is knowledge of the Hour. So doubt ye not concerning it, but follow Me. This is the right path.

(109) When Jesus came with clear proofs (of Allah's Sovereignty), he said: I have come unto you with wisdom, and to make plain some of that concerning which ye differ. So keep your duty to Allah, and obey me.

(110) And gave them plain commandments. And they differed not until after the knowledge came unto them, through rivalry among themselves. Lo! thy Lord will judge between them on the Day of Resurrection concerning that wherein they used to differ.
