The word(s) "where" appears 156 time(s) in 144 verse(s) in Quran in Mohsin Khan translation.

(51) And wherein is beauty for you, when you bring them home in the evening, and as you lead them forth to pasture in the morning.

(52) Then, on the Day of Resurrection, He will disgrace them and will say: "where are My (so called) partners concerning whom you used to disagree and dispute (with the believers, by defying and disobeying Allah)?" Those who have been given the knowledge (about the Torment of Allah for the disbelievers) will say: "Verily! Disgrace and misery this Day are upon the disbelievers.

(53) In order that He may make manifest to them the truth of that wherein they differ, and that those who disbelieved (in Resurrection, and in the Oneness of Allah) may know that they were liars.

(54) He hides himself from the people because of the evil of that whereof he has been informed. Shall he keep her with dishonour or bury her in the earth ? Certainly, evil is their decision.

(55) "Then, eat of all fruits, and follow the ways of your Lord made easy (for you)." There comes forth from their bellies, a drink of varying colour wherein is healing for men. Verily, in this is indeed a sign for people who think.

(56) And be not like her who undoes the thread which she has spun, after it has become strong, by taking your oaths as a means of deception among yourselves, lest a nation should be more numerous than another nation. Allah only tests you by this [i.e who obeys Allah and fulfils Allah's Covenant and who disobeys Allah and breaks Allah's Covenant]. And on the Day of Resurrection, He will certainly make clear to you that wherein you used to differ [i.e. a believer confesses and believes in the Oneness of Allah and in the Prophethood of Prophet Muhammad صلى الله عليه و سلم which the disbeliever denies and that is their difference amongst them in the life of this world] .

(57) The Sabbath was only prescribed for those who differed concerning it, and verily, your Lord will judge between them on the Day of Resurrection about that wherein they used to differ.

(58) Glorified (and Exalted) be He (Allah) [above all that (evil) they associate with Him] Who took His slave (Muhammad صلى الله عليه و سلم) for a journey by night from Al-Masjid-al-Haram (at Makkah) to Al-Masjid-al-Aqsa (in Jerusalem), the neighbourhood whereof We have blessed, in order that We might show him (Muhammad صلى الله عليه و سلم) of Our Ayat (proofs, evidence, lessons, signs, etc.). Verily, He is the All-Hearer, the All-Seer .

(59) See they not that Allah, Who created the heavens and the earth, is Able to create the like of them. And He has decreed for them an appointed term, whereof there is no doubt. But the Zalimun (polytheists and wrong-doers) refuse (the truth - the Message of Islamic Monotheism, and accept nothing) but disbelief.

(60) And you would have thought them awake, whereas they were asleep. And We turned them on their right and on their left sides, and their dog stretching forth his two forelegs at the entrance [of the Cave or in the space near to the entrance of the Cave (as a guard at the gate)]. Had you looked at them, you would certainly have turned back from them in flight, and would certainly have been filled with awe of them.
