The word(s) "whether" appears 56 time(s) in 53 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) As to those who reject Faith, it is the same to them whether thou warn them or do not warn them; they will not believe.

(2) O ye who believe! When ye deal with each other, in transactions involving future obligations in a fixed period of time, reduce them to writing Let a scribe write down faithfully as between the parties: let not the scribe refuse to write: as Allah Has taught him, so let him write. Let him who incurs the liability dictate, but let him fear His Lord Allah, and not diminish aught of what he owes. If they party liable is mentally deficient, or weak, or unable Himself to dictate, Let his guardian dictate faithfully, and get two witnesses, out of your own men, and if there are not two men, then a man and two women, such as ye choose, for witnesses, so that if one of them errs, the other can remind her. The witnesses should not refuse when they are called on (For evidence). Disdain not to reduce to writing (your contract) for a future period, whether it be small or big: it is juster in the sight of Allah, More suitable as evidence, and more convenient to prevent doubts among yourselves but if it be a transaction which ye carry out on the spot among yourselves, there is no blame on you if ye reduce it not to writing. But take witness whenever ye make a commercial contract; and let neither scribe nor witness suffer harm. If ye do (such harm), it would be wickedness in you. And fear Allah. And Allah teaches you. And Allah is well acquainted with all things.

(3) To Allah belongeth all that is in the heavens and on earth. whether ye show what is in your minds or conceal it, Allah Calleth you to account for it. He forgiveth whom He pleaseth, and punisheth whom He pleaseth, for Allah hath power over all things.

(4) Say: "whether ye hide what is in your hearts or reveal it, Allah knows it all: He knows what is in the heavens, and what is on earth. And Allah has power over all things.

(5) Not for thee, (but for Allah), is the decision: whether He turn in mercy to them, or punish them; for they are indeed wrong-doers.

(6) Those who spend (freely), whether in prosperity, or in adversity; who restrain anger, and pardon (all) men;- for Allah loves those who do good;-

(7) From what is left by parents and those nearest related there is a share for men and a share for women, whether the property be small or large,-a determinate share.

(8) Allah (thus) directs you as regards your Children's (Inheritance): to the male, a portion equal to that of two females: if only daughters, two or more, their share is two-thirds of the inheritance; if only one, her share is a half. For parents, a sixth share of the inheritance to each, if the deceased left children; if no children, and the parents are the (only) heirs, the mother has a third; if the deceased Left brothers (or sisters) the mother has a sixth. (The distribution in all cases ('s) after the payment of legacies and debts. Ye know not whether your parents or your children are nearest to you in benefit. These are settled portions ordained by Allah; and Allah is All-knowing, Al-wise.

(9) Let those fight in the cause of Allah Who sell the life of this world for the hereafter. To him who fighteth in the cause of Allah,- whether he is slain or gets victory - Soon shall We give him a reward of great (value).

(10) O ye who believe! stand out firmly for justice, as witnesses to Allah, even as against yourselves, or your parents, or your kin, and whether it be (against) rich or poor: for Allah can best protect both. Follow not the lusts (of your hearts), lest ye swerve, and if ye distort (justice) or decline to do justice, verily Allah is well-acquainted with all that ye do.
