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

(41) They are those for whom there will be an evil torment (in this world). And in the Hereafter they will be the greatest losers.

(42) One with whom was knowledge of the Scripture said: "I will bring it to you within the twinkling of an eye!" Then when he [Sulaiman (Solomon)] saw it placed before him, he said: "This is by the Grace of my Lord - to test me whether I am grateful or ungrateful! And whoever is grateful, truly, his gratitude is for (the good of) his ownself; and whoever is ungrateful, (he is ungrateful only for the loss of his ownself). Certainly my Lord is Rich (Free of all needs), Bountiful."

(43) They said: "We augur ill omen from you and those with you." He said: "Your ill omen is with Allah; nay, but you are a people that are being tested."

(44) Do people think that they will be left alone because they say: "We believe," and will not be tested.

(45) And We indeed tested those who were before them. And Allah will certainly make (it) known (the truth of) those who are true, and will certainly make (it) known (the falsehood of) those who are liars, (although Allah knows all that before putting them to test).

(46) Verily, Allah knows those who believe, and verily, He knows the hypocrites [i.e. Allah will test the people with good and hard days to discriminate the good from the wicked, although Allah knows all that before putting them to test].

(47) And he (Iblis - Satan) had no authority over them, - except that We might test him who believes in the Hereafter from him who is in doubt about it. And your Lord is a Hafiz (Watchful) over everything. (All-Knower of everything i.e. He keeps record of every person as regards deeds, and then He will reward them accordingly).

(48) Till, when they reach it (Hell-fire), their hearing (ears) and their eyes, and their skins will testify against them as to what they used to do.

(49) And they will say to their skins, "Why do you testify against us?" They will say: "Allah has caused us to speak as He causes all things to speak: and He created you the first time, and to Him you are made to return."

(50) And you have not been hiding yourselves (in the world), lest your ears, and your eyes, and your skins should testify against you; but you thought that Allah knew not much of what you were doing.
