The word(s) "alone" appears 44 time(s) in 41 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) When they meet those who believe, they say: "We believe;" but when they are alone with their evil ones, they say: "We are really with you: We (were) only jesting."

(2) And believe in what I reveal, confirming the revelation which is with you, and be not the first to reject Faith therein, nor sell My Signs for a small price; and fear Me, and Me alone.

(3) The Truth (comes) from Allah alone; so be not of those who doubt.

(4) Ah! ye are those who love them, but they love you not,- though ye believe in the whole of the Book. When they meet you, they say, "We believe": But when they are alone, they bite off the very tips of their fingers at you in their rage. Say: "Perish in your rage; Allah knoweth well all the secrets of the heart."

(5) If two men among you are guilty of lewdness, punish them both. If they repent and amend, Leave them alone; for Allah is Oft-returning, Most Merciful.

(6) Knowest thou not that to Allah (alone) belongeth the dominion of the heavens and the earth? He punisheth whom He pleaseth, and He forgiveth whom He pleaseth: and Allah hath power over all things.

(7) Leave alone those who take their religion to be mere play and amusement, and are deceived by the life of this world. But proclaim (to them) this (truth): that every soul delivers itself to ruin by its own acts: it will find for itself no protector or intercessor except Allah: if it offered every ransom, (or reparation), none will be accepted: such is (the end of) those who deliver themselves to ruin by their own acts: they will have for drink (only) boiling water, and for punishment, one most grievous: for they persisted in rejecting Allah.

(8) "And behold! ye come to us bare and alone as We created you for the first time: ye have left behind you all (the favours) which We bestowed on you: We see not with you your intercessors whom ye thought to be partners in your affairs: so now all relations between you have been cut off, and your (pet) fancies have left you in the lurch!"

(9) Likewise did We make for every Messenger an enemy,- evil ones among men and jinns, inspiring each other with flowery discourses by way of deception. If thy Lord had so planned, they would not have done it: so leave them and their inventions alone.

(10) Even so, in the eyes of most of the pagans, their "partners" made alluring the slaughter of their children, in order to lead them to their own destruction, and cause confusion in their religion. If Allah had willed, they would not have done so: But leave alone them and their inventions.
