The word(s) "test" appears 76 time(s) in 70 verse(s) in Quran in Muhammad Pickthal translation.

(1) Or say ye that Abraham, and Ishmael, and Isaac, and Jacob, and the tribes were Jews or Christians? Say: Do ye know best, or doth Allah? And who is more unjust than he who hideth a testimony which he hath received from Allah? Allah is not unaware of what ye do.

(2) Thus We have appointed you a middle nation, that ye may be witnesses against mankind, and that the messenger may be a witness against you. And We appointed the qiblah which ye formerly observed only that We might know him who followeth the messenger, from him who turneth on his heels. In truth it was a hard (test) save for those whom Allah guided. But it was not Allah's purpose that your faith should be in vain, for Allah is Full of Pity, Merciful toward mankind.

(3) And even if thou broughtest unto those who have received the Scripture all kinds of portents, they would not follow thy qiblah, nor canst thou be a follower of their qiblah; nor are some of them followers of the qiblah of others. And if thou shouldst follow their desires after the knowledge which hath come unto thee, then surely wert thou of the evil-doers.

(4) But he who feareth from a testator some unjust or sinful clause, and maketh peace between the parties, (it shall be) no sin for him. Lo! Allah is Forgiving, Merciful.

(5) O ye who believe! When ye contract a debt for a fixed term, record it in writing. Let a scribe record it in writing between you in (terms of) equity. No scribe should refuse to write as Allah hath taught him, so let him write, and let him who incurreth the debt dictate, and let him observe his duty to Allah his Lord, and diminish naught thereof. But if he who oweth the debt is of low understanding, or weak, or unable himself to dictate, then let the guardian of his interests dictate in (terms of) equity. And call to witness, from among your men, two witnesses. And if two men be not (at hand) then a man and two women, of such as ye approve as witnesses, so that if the one erreth (through forgetfulness) the other will remember. And the witnesses must not refuse when they are summoned. Be not averse to writing down (the contract) whether it be small or great, with (record of) the term thereof. That is more equitable in the sight of Allah and more sure for testimony, and the best way of avoiding doubt between you; save only in the case when it is actual merchandise which ye transfer among yourselves from hand to hand. In that case it is no sin for you if ye write it not. And have witnesses when ye sell one to another, and let no harm be done to scribe or witness. If ye do (harm to them) lo! it is a sin in you. Observe your duty to Allah. Allah is teaching you. And Allah is knower of all things.

(6) If ye be on a journey and cannot find a scribe, then a pledge in hand (shall suffice). And if one of you entrusteth to another let him who is trusted deliver up that which is entrusted to him (according to the pact between them) and let him observe his duty to Allah his Lord. Hide not testimony. He who hideth it, verily his heart is sinful. Allah is Aware of what ye do.

(7) Say: O Allah! Owner of Sovereignty! Thou givest sovereignty unto whom Thou wilt, and Thou withdrawest sovereignty from whom Thou wilt. Thou exaltest whom Thou wilt, and Thou abasest whom Thou wilt. In Thy hand is the good. Lo! Thou art Able to do all things.

(8) As for those of your women who are guilty of lewdness, call to witness four of you against them. And if they testify (to the truth of the allegation) then confine them to the houses until death take them or (until) Allah appoint for them a way (through new legislation).

(9) But Allah (Himself) testifieth concerning that which He hath revealeth unto thee; in His knowledge hath He revealed it; and the angels also testify. And Allah is sufficient Witness.

(10) O ye who believe! Let there be witnesses between you when death draweth nigh unto one of you, at the time of bequest - two witnesses, just men from among you, or two others from another tribe, in case ye are campaigning in the land and the calamity of death befall you. Ye shall empanel them both after the prayer, and, if ye doubt, they shall be made to swear by Allah (saying): We will not take a bribe, even though it were (on behalf of) a near kinsman nor will we hide the testimony of Allah, for then indeed we should be of the sinful.
