The word(s) "why" appears 62 time(s) in 59 verse(s) in Quran in Muhammad Habib Shakir translation.

(41) But (now) when the truth has come to them from Us, they say: why is he not given the like of what was given to Musa? What! did they not disbelieve in what Musa was given before? They say: Two magicians backing up each other; and they say: Surely we are unbelievers in all.

(42) And they say: why are not signs sent down upon him from his Lord? Say: The signs are only with Allah, and I am only a plain warner.

(43) And they shall say to their skins: why have you borne witness against us? They shall say: Allah Who makes everything speak has made us speak, and He created you at first, and to Him you shall be brought back.

(44) And if We had made it a Quran in a foreign tongue, they would certainly have said: why have not its communications been made clear? What! a foreign (tongue) and an Arabian! Say: It is to those who believe a guidance and a healing; and (as for) those who do not believe, there is a heaviness in their ears and it is obscure to them; these shall be called to from a far-off place.

(45) And they say: why was not this Quran revealed to a man of importance in the two towns?

(46) But why have not bracelets of gold been put upon him, or why have there not come with him angels as companions?

(47) why did not then those help them whom they took for gods besides Allah to draw (them) nigh (to Him)? Nay! they were lost to them; and this was their lie and what they forged.

(48) And those who believe say: why has not a chapter been revealed? But when a decisive chapter is revealed, and fighting is mentioned therein you see those in whose hearts is a disease look to you with the look of one fainting because of death. Woe to them then!

(49) We have created you, why do you not then assent?

(50) And certainly you know the first growth, why do you not then mind?
