The word(s) "fit" appears 106 time(s) in 104 verse(s) in Quran in Abdullah Yusuf Ali translation.

(71) Thus did the (generations) before them say! But all that they did was of no profit to them.

(72) "Without doubt ye do call me to one who is not fit to be called to, whether in this world, or in the Hereafter; our return will be to Allah; and the Transgressors will be Companions of the Fire!

(73) The Day when no profit will it be to Wrong-doers to present their excuses, but they will (only) have the Curse and the Home of Misery.

(74) Do they not travel through the earth and see what was the End of those before them? They were more numerous than these and superior in strength and in the traces (they have left) in the land: Yet all that they accomplished was of no profit to them.

(75) But their professing the Faith when they (actually) saw Our Punishment was not going to profit them. (Such has been) Allah's Way of dealing with His Servants (from the most ancient times). And even thus did the Rejecters of Allah perish (utterly)!

(76) Such is the requital of the enemies of Allah,- the Fire: therein will be for them the Eternal Home: a (fit) requital, for that they were wont to reject Our Signs.

(77) Whoever works righteousness benefits his own soul; whoever works evil, it is against his own soul: nor is thy Lord ever unjust (in the least) to His Servants.

(78) It is not fitting for a man that Allah should speak to him except by inspiration, or from behind a veil, or by the sending of a messenger to reveal, with Allah's permission, what Allah wills: for He is Most High, Most Wise.

(79) In front of them is Hell: and of no profit to them is anything they may have earned, nor any protectors they may have taken to themselves besides Allah: for them is a tremendous Penalty.

(80) If any one does a righteous deed, it ensures to the benefit of his own soul; if he does evil, it works against (his own soul). In the end will ye (all) be brought back to your Lord.
