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

(11) They said: "Comest thou to us, that we may worship Allah alone, and give up the cult of our fathers? bring us what thou threatenest us with, if so be that thou tellest the truth!"

(12) If it had been Our will, We should have elevated him with Our signs; but he inclined to the earth, and followed his own vain desires. His similitude is that of a dog: if you attack him, he lolls out his tongue, or if you leave him alone, he (still) lolls out his tongue. That is the similitude of those who reject Our signs; So relate the story; perchance they may reflect.

(13) They ask thee about the (final) Hour - when will be its appointed time? Say: "The knowledge thereof is with my Lord (alone): None but He can reveal as to when it will occur. Heavy were its burden through the heavens and the earth. Only, all of a sudden will it come to you." They ask thee as if thou Wert eager in search thereof: Say: "The knowledge thereof is with Allah (alone), but most men know not."

(14) They will swear to you by Allah, when ye return to them, that ye may leave them alone. So leave them alone: For they are an abomination, and Hell is their dwelling-place,-a fitting recompense for the (evil) that they did.

(15) "Slay ye Joseph or cast him out to some (unknown) land, that so the favour of your father may be given to you alone: (there will be time enough) for you to be righteous after that!"

(16) They stained his shirt with false blood. He said: "Nay, but your minds have made up a tale (that may pass) with you, (for me) patience is most fitting: Against that which ye assert, it is Allah (alone) Whose help can be sought"..

(17) For Him (alone) is prayer in Truth: any others that they call upon besides Him hear them no more than if they were to stretch forth their hands for water to reach their mouths but it reaches them not: for the prayer of those without Faith is nothing but (futile) wandering (in the mind).

(18) Leave them alone, to enjoy (the good things of this life) and to please themselves: let (false) hope amuse them: soon will knowledge (undeceive them).

(19) Allah has said: "Take not (for worship) two gods: for He is just One Allah: then fear Me (and Me alone)."

(20) And We put coverings over their hearts (and minds) lest they should understand the Qur'an, and deafness into their ears: when thou dost commemorate thy Lord and Him alone in the Qur'an, they turn on their backs, fleeing (from the Truth).
