The word(s) "alone" appears 38 time(s) in 38 verse(s) in Quran in Muhammad Habib Shakir translation.

(31) But when they saw Our punishment, they said: We believe in Allah alone and we deny what we used to associate with Him.

(32) And if you do not believe in me, then leave me alone.

(33) Indeed, there is for you a good example in Ibrahim and those with him when they said to their people: Surely we are clear of you and of what you serve besides Allah; we declare ourselves to be clear of you, and enmity and hatred have appeared between us and you forever until you believe in Allah alone-- but not in what Ibrahim said to his father: I would certainly ask forgiveness for you, and I do not control for you aught from Allah-- Our Lord! on Thee do we rely, and to Thee do we turn, and to Thee is the eventual coming:

(34) Therefore leave them alone to go on with the false discourses and to sport until they come face to face with that day of theirs with which they are threatened;

(35) Leave Me and him whom I created alone,

(36) With your Lord alone shall on that day be the place of rest.

(37) So grant the unbelievers a respite: let them alone for a while.

(38) So Allah's apostle said to them (Leave alone) Allah's she-camel, and (give) her (to) drink.
