The word(s) "whether" appears 29 time(s) in 25 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) Surely those who disbelieve, it being alike to them whether you warn them, or do not warn them, will not believe.

(2) O you who believe! when you deal with each other in contracting a debt for a fixed time, then write it down; and let a scribe write it down between you with fairness; and the scribe should not refuse to write as Allah has taught him, so he should write; and let him who owes the debt dictate, and he should be careful of (his duty to) Allah, his Lord, and not diminish anything from it; but if he who owes the debt is unsound in understanding, or weak, or (if) he is not able to dictate himself, let his guardian dictate with fairness; and call in to witness from among your men two witnesses; but if there are not two men, then one man and two women from among those whom you choose to be witnesses, so that if one of the two errs, the second of the two may remind the other; and the witnesses should not refuse when they are summoned; and be not averse to writing it (whether it is) small or large, with the time of its falling due; this is more equitable in the sight of Allah and assures greater accuracy in testimony, and the nearest (way) that you may not entertain doubts (afterwards), except when it is ready merchandise which you give and take among yourselves from hand to hand, then there is no blame on you in not writing it down; and have witnesses when you barter with one another, and let no harm be done to the scribe or to the witness; and if you do (it) then surely it will be a transgression in you, and be careful of (your duty) to Allah, Allah teaches you, and Allah knows all things.

(3) Whatever is in the heavens and whatever is in the earth is Allah's; and whether you manifest what is in your minds or hide it, Allah will call you to account according to it; then He will forgive whom He pleases and chastise whom He pleases, and Allah has power over all things.

(4) Say: whether you hide what is in your hearts or manifest it, Allah knows it, and He knows whatever is in the heavens and whatever is in the earth, and Allah has power over all things.

(5) You have no concern in the affair whether He turns to them (mercifully) or chastises them, for surely they are unjust.

(6) So their Lord accepted their prayer: That I will not waste the work of a worker among you, whether male or female, the one of you being from the other; they, therefore, who fled and were turned out of their homes and persecuted in My way and who fought and were slain, I will most certainly cover their evil deeds, and I will most certainly make them enter gardens beneath which rivers flow; a reward from Allah, and with Allah is yet better reward.

(7) Men shall have a portion of what the parents and the near relatives leave, and women shall have a portion of what the parents and the near relatives leave, whether there is little or much of it; a stated portion.

(8) And whoever does good deeds whether male or female and he (or she) is a believer-- these shall enter the garden, and they shall not be dealt with a jot unjustly.

(9) And if you invite them to guidance, they will not follow you; it is the same to you whether you invite them or you are silent.

(10) And others are made to await Allah's command, whether He chastise them or whether He turn to them (mercifully), and Allah is Knowing, Wise.
