The word(s) "fit" appears 84 time(s) in 82 verse(s) in Quran in Mohsin Khan translation.

(51) Make not the calling of the Messenger (Muhammad صلى الله عليه وسلم) among you as your calling one of another. Allah knows those of you who slip away under shelter (of some excuse without taking the permission to leave, from the Messenger (صلى الله عليه وسلم). And let those who oppose the Messenger's (Muhammad صلى الله عليه وسلم) commandment (i.e. his Sunnah - legal ways, orders, acts of worship, statements) (among the sects) beware, lest some fitnah (disbelief, trials, afflictions, earthquakes, killing, overpowered by a tyrant) should befall them or a painful torment be inflicted on them.

(52) Yet they have taken besides Him other alihah (gods) who created nothing but are themselves created, and possess neither harm nor benefit for themselves, and possess no power (of causing) death, nor (of giving) life, nor of raising the dead.

(53) And they (disbelievers, polytheists) worship besides Allah that which can neither profit them nor harm them; and the disbeliever is ever a helper (of the Satan) against his Lord.

(54) "Or do they benefit you or do they harm (you)?"

(55) Verily, you cannot make the dead to hear nor can you make the deaf to hear the call (i.e. benefit them and similarly the disbelievers), when they flee, turning their backs.

(56) And the wife of Fir'aun (Pharaoh) said: "A comfort of the eye for me and for you. Kill him not, perhaps he may be of benefit to us, or we may adopt him as a son." And they perceived not (the result of that).

(57) So set you (O Muhammad صلى الله عليه وسلم) your face towards the religion (of pure Islamic Monotheism) Hanif (worship none but Allah Alone). Allah's fitrah (i.e. Allah's Islamic Monotheism) with which He has created mankind. No change let there be in Khalq-illah (i.e. the religion of Allah - Islamic Monotheism): that is the straight religion, but most of men know not. [Tafsir At-Tabari]

(58) Say: "On the Day of Al-Fath (Decision), no profit will it be to those who disbelieve if they (then) believe! Nor will they be granted a respite."

(59) And if the enemy had entered from all sides (of the city), and they had been exhorted to Al-fitnah (i.e. to renegade from Islam to polytheism), they would surely have committed it and would have hesitated thereupon but little.

(60) Intercession with Him profits not except for him whom He permits. So much so that when fear is banished from their (angels') hearts, they (angels) say: "What is it that your Lord has said?" They say: "The truth. And He is the Most High, the Most Great."
