The word(s) "quarrelsome" appears 4 time(s) in 4 verse(s) in Quran in Mohsin Khan translation.

(1) And of mankind there is he whose speech may please you (O Muhammad صلى الله عليه وسلم), in this worldly life, and he calls Allah to witness as to that which is in his heart, yet he is the most quarrelsome of the opponents.

(2) And indeed We have put forth every kind of example in this Qur'an, for mankind. But, man is ever more quarrelsome than anything.

(3) So We have made this (the Qur'an) easy in your own tongue (O Muhammad صلى الله عليه وسلم), only that you may give glad tidings to the Muttaqun (the pious - See V.2:2), and warn with it the Ludd (most quarrelsome) people.

(4) And say: "Are our alihah (gods) better or is he ['Îsa (Jesus)]?" They quoted not the above example except for argument. Nay! But they are a quarrelsome people. (See V. 21:98-101)
