The word(s) "both" appears 117 time(s) in 111 verse(s) in Quran in Mohsin Khan translation.

(21) It is He Who has created you from a single person (Adam), and (then) He has created from him his wife [Hawwa' (Eve)], in order that he might enjoy the pleasure of living with her. When he (a polytheist from Adam's offspring - as stated by Ibn Kathir in his Tafsir) had sexual relation with her (the polytheist's wife), she became pregnant and she carried it about lightly. Then when it became heavy, they both invoked Allah, their Lord (saying): "If You give us a Salih (good in every aspect) child, we shall indeed be among the grateful."

(22) O you who believe! When you meet (an enemy) force, take a firm stand against them and remember the Name of Allah much (both with tongue and mind), so that you may be successful.

(23) Allah said: "Verily, the invocation of you both is accepted. So you both keep to the Straight Way (i.e. keep on doing good deeds and preaching Allah's Message with patience), and follow not the path of those who know not (the truth i.e. to believe in the Oneness of Allah, and also to believe in the Reward of Allah: Paradise)."

(24) So they raced with one another to the door, and she tore his shirt from the back. They both found her lord (i.e. her husband) at the door. She said: "What is the recompense (punishment) for him who intended an evil design against your wife, except that he be put in prison or a painful torment?"

(25) "O two companions of the prison! As for one of you, he (as a servant) will pour out wine for his lord (king or master) to drink; and as for the other, he will be crucified and birds will eat from his head. Thus is the case judged concerning which you both did inquire."

(26) And He has made the sun and the moon, both constantly pursuing their courses, to be of service to you; and He has made the night and the day, to be of service to you.

(27) So, We took vengeance on them. They are both on an open highway, plain to see.

(28) And your Lord has decreed that you worship none but Him. And that you be dutiful to your parents. If one of them or both of them attain old age in your life, say not to them a word of disrespect, nor shout at them but address them in terms of honour.

(29) And put forward to them the example of two men: unto one of them We had given two gardens of grapes, and We had surrounded both with date-palms; and had put between them green crops (cultivated fields).

(30) So they both proceeded, till, when they embarked the ship, he (Khidr) scuttled it. Musa (Moses) said: "Have you scuttled it in order to drown its people? Verily, you have committed a thing "Imr" (a Munkar - evil, bad, dreadful thing)."
