The word(s) "alone" appears 31 time(s) in 30 verse(s) in Quran in Saheeh International translation.

(1) And when they meet those who believe, they say, "We believe"; but when they are alone with their evil ones, they say, "Indeed, we are with you; we were only mockers."

(2) And when they meet those who believe, they say, "We have believed"; but when they are alone with one another, they say, "Do you talk to them about what Allah has revealed to you so they can argue with you about it before your Lord?" Then will you not reason?

(3) Say, [O Muhammad], "If the home of the Hereafter with Allah is for you alone and not the [other] people, then wish for death, if you should be truthful.

(4) [Mention] when Allah said, "O Jesus, indeed I will take you and raise you to Myself and purify you from those who disbelieve and make those who follow you [in submission to Allah alone] superior to those who disbelieve until the Day of Resurrection. Then to Me is your return, and I will judge between you concerning that in which you used to differ.

(5) Here you are loving them but they are not loving you, while you believe in the Scripture - all of it. And when they meet you, they say, "We believe." But when they are alone, they bite their fingertips at you in rage. Say, "Die in your rage. Indeed, Allah is Knowing of that within the breasts."

(6) Allah instructs you concerning your children: for the male, what is equal to the share of two females. But if there are [only] daughters, two or more, for them is two thirds of one's estate. And if there is only one, for her is half. And for one's parents, to each one of them is a sixth of his estate if he left children. But if he had no children and the parents [alone] inherit from him, then for his mother is one third. And if he had brothers [or sisters], for his mother is a sixth, after any bequest he [may have] made or debt. Your parents or your children - you know not which of them are nearest to you in benefit. [These shares are] an obligation [imposed] by Allah. Indeed, Allah is ever Knowing and Wise.

(7) And the two who commit it among you, dishonor them both. But if they repent and correct themselves, leave them alone. Indeed, Allah is ever Accepting of repentance and Merciful.

(8) And they say, "[We pledge] obedience." But when they leave you, a group of them spend the night determining to do other than what you say. But Allah records what they plan by night. So leave them alone and rely upon Allah. And sufficient is Allah as Disposer of affairs.

(9) No, it is Him [alone] you would invoke, and He would remove that for which you invoked Him if He willed, and you would forget what you associate [with Him].

(10) [It will be said to them], "And you have certainly come to Us alone as We created you the first time, and you have left whatever We bestowed upon you behind you. And We do not see with you your 'intercessors' which you claimed that they were among you associates [of Allah]. It has [all] been severed between you, and lost from you is what you used to claim."
