The word(s) "test" appears 78 time(s) in 68 verse(s) in Quran in Mohsin Khan translation.

(31) Say (O Muhammad صلى الله عليه وسلم): "Shall We tell you the greatest losers in respect of (their) deeds?

(32) And strain not your eyes in longing for the things We have given for enjoyment to various groups of them (polytheists and disbelievers in the Oneness of Allah), the splendour of the life of this world, that We may test them thereby. But the provision (good reward in the Hereafter) of your Lord is better and more lasting.

(33) They said: "Then bring him before the eyes of the people, that they may testify."

(34) They shall not hear the slightest sound of it (Hell), while they abide in that which their ownselves desire.

(35) The greatest terror (on the Day of Resurrection) will not grieve them, and the angels will meet them, (with the greeting): "This is your Day which you were promised."

(36) Verily, in this [what We did as regards drowning of the people of Nuh (Noah)], there are indeed Ayat (proofs, evidence, lessons, signs, etc. for men to understand), for sure We are ever putting (men) to the test.

(37) And those who accuse chaste women, and produce not four witnesses, flog them with eighty stripes, and reject their testimony forever. They indeed are the Fasiqun (liars, rebellious, disobedient to Allah).

(38) And for those who accuse their wives, but have no witnesses except themselves, let the testimony of one of them be four testimonies (i.e. testifies four times) by Allah that he is one of those who speak the truth.

(39) And the fifth (testimony should be) the invoking of the Curse of Allah on him if he be of those who tell a lie (against her).

(40) And the fifth (testimony) should be that the Wrath of Allah be upon her if he (her husband) speaks the truth.
