The word(s) "whether" appears 42 time(s) in 39 verse(s) in Quran in Mohsin Khan translation.

(31) "Whosoever does an evil deed, will not be requited except the like thereof; and whosoever does a righteous deed, whether male or female and is a true believer (in the Oneness of Allah), such will enter Paradise, where they will be provided therein (with all things in abundance) without limit.

(32) So be patient (O Muhammad صلى الله عليه وسلم); verily, the Promise of Allah is true and whether We show you (O Muhammad صلى الله عليه وسلم in this world) some part of what We have promised them, or We cause you to die then still it is to Us they all shall be returned.

(33) Taste you therein its heat and whether you are patient of it or impatient of it, it is all the same. You are only being requited for what you used to do.

(34) It is equal to them whether you (Muhammad صلى الله عليه وسلم) ask forgiveness or ask not forgiveness for them, Allah will never forgive them. Verily, Allah guides not the people who are the Fasiqin (rebellious, disobedient to Allah).

(35) And those of your women as have passed the age of monthly courses, for them the 'Iddah (prescribed period), if you have doubt (about their periods), is three months; and for those who have no courses [(i.e. they are still immature) their 'Iddah (prescribed period) is three months likewise, except in case of death] . And for those who are pregnant (whether they are divorced or their husbands are dead), their 'Iddah (prescribed period) is until they lay down their burden; and whosoever fears Allah and keeps his duty to Him, He will make his matter easy for him.

(36) And whether you keep your talk secret or disclose it, Verily, He is the All-Knower of what is in the breasts (of men).

(37) 'And we know not whether evil is intended for those on earth, or whether their Lord intends for them a Right Path.

(38) Say (O Muhammad صلى الله عليه وسلم): "I know not whether (the punishment) which you are promised is near or whether my Lord will appoint for it a distant term.

(39) Verily, We showed him the way, whether he be grateful or ungrateful.
