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

(11) And when affliction touches a man, he calls on Us, whether lying on his side or sitting or standing; but when We remove his affliction from him, he passes on as though he had never called on Us on account of an affliction that touched him; thus that which they do is made fair-seeming to the extravagant.

(12) And they shall all come forth before Allah, then the weak shall say to those who were proud: Surely we were your followers, can you therefore avert from us any part of the chastisement of Allah? They would say: If Allah had guided us, we too would have guided you; it is the same to us whether we are impatient (now) or patient, there is no place for us to fly to.

(13) Whoever does good whether male or female and he is a believer, We will most certainly make him live a happy life, and We will most certainly give them their reward for the best of what they did.

(14) But if they turn back, say: I have given you warning in fairness and I do not know whether what you are threatened with is near or far;

(15) They said: It is the same to us whether you admonish or are not one of the admonishers

(16) He said: We will see whether you have told the truth or whether you are of the liars:

(17) One who had the knowledge of the Book said: I will bring it to you in the twinkling of an eye. Then when he saw it settled beside him, he said: This is of the grace of my Lord that He may try me whether I am grateful or ungrateful; and whoever is grateful, he is grateful only for his own soul, and whoever is ungrateful, then surely my Lord is Self-sufficient, Honored.

(18) He said: Alter her throne for her, we will see whether she follows the right way or is of those who do not go aright.

(19) And it is alike to them whether you warn them or warn them not: they do not believe.

(20) Then ask them whether they are stronger in creation or those (others) whom We have created. Surely We created them of firm clay.
