The word(s) "engage" appears 5 time(s) in 5 verse(s) in Quran in Mohsin Khan translation.

(1) And believe no one except the one who follows your religion. Say (O Muhammad صلى الله عليه وسلم): "Verily! Right guidance is the Guidance of Allah" and do not believe that anyone can receive like that which you have received, otherwise they would engage you in argument before your Lord. Say (O Muhammad صلى الله عليه وسلم): "All the bounty is in the Hand of Allah; He grants to whom He wills. And Allah is All-Sufficient for His creatures' needs, All-Knower."

(2) And it has already been revealed to you in the Book (this Qur'an) that when you hear the Verses of Allah being denied and mocked at, then sit not with them, until they engage in a talk other than that; (but if you stayed with them) certainly in that case you would be like them. Surely, Allah will collect the hypocrites and disbelievers all together in Hell.

(3) And when you (Muhammad صلى الله عليه وسلم) see those who engage in a false conversation about Our Verses (of the Qur'an) by mocking at them, stay away from them till they turn to another topic. And if Shaitan (Satan) causes you to forget, then after the remembrance sit not you in the company of those people who are the Zalimun (polytheists and wrong-doers).

(4) [Musa (Moses) added:] "Verily, these people will be destroyed for that which they are engaged in (idols-worship). And all that they are doing is in vain."

(5) Whosoever is in the heavens and on earth begs of Him (its needs from Him). Every day He is (engaged) in some affair (such as giving honour or disgrace to some, life or death to some, etc.)!
