The word(s) "rear" appears 6 time(s) in 6 verse(s) in Quran in Mohsin Khan translation.

(1) (And remember) when you ran away (dreadfully) without even casting a side glance at anyone, and the Messenger (Muhammad صلى الله عليه وسلم) was in your rear calling you back. There did Allah give you one distress after another by way of requital to teach you not to grieve for that which had escaped you, nor for that which had befallen you. And Allah is Well-Aware of all that you do.

(2) When you (O Messenger Muhammad صلى الله عليه وسلم) are among them, and lead them in As-Salat (the prayer), let one party of them stand up [in Salat (prayer)] with you taking their arms with them; when they finish their prostrations, let them take their positions in the rear and let the other party come up which have not yet prayed, and let them pray with you taking all the precautions and bearing arms. Those who disbelieve wish, if you were negligent of your arms and your baggage, to attack you in a single rush, but there is no sin on you if you put away your arms because of the inconvenience of rain or because you are ill, but take every precaution for yourselves. Verily, Allah has prepared a humiliating torment for the disbelievers.

(3) O you who believe! When you intend to offer As-Salat (the prayer), wash your faces and your hands (forearms) up to the elbows, rub (by passing wet hands over) your heads, and (wash) your feet up to ankles . If you are in a state of Janaba (i.e. after a sexual discharge), purify yourselves (bathe your whole body). But if you are ill or on a journey, or any of you comes after answering the call of nature, or you have been in contact with women (i.e. sexual intercourse), and you find no water, then perform Tayammum with clean earth and rub therewith your faces and hands. Allah does not want to place you in difficulty, but He wants to purify you, and to complete His Favour to you that you may be thankful.

(4) "Then travel in a part of the night with your family, and you go behind them in the rear, and let no one amongst you look back, but go on to where you are ordered."

(5) And We had already forbidden (other) foster suckling mothers for him, until she (his sister came up and) said: "Shall I direct you to a household who will rear him for you, and look after him in a good manner?"

(6) On the Day when the hypocrites - men and women - will say to the believers: "Wait for us! Let us get something from your light!" It will be said: "Go back to your rear! Then seek a light!" So a wall will be put up between them, with a gate therein. Inside it will be mercy, and outside it will be torment."
