The word(s) "alone" appears 187 time(s) in 174 verse(s) in Quran in Mohsin Khan translation.

(31) It is those who believe (in the Oneness of Allah and worship none but Him alone) and confuse not their belief with Zulm (wrong i.e. by worshipping others besides Allah), for them (only) there is security and they are the guided.

(32) And truly you have come unto Us alone (without wealth, companions or anything else) as We created you the first time. You have left behind you all that which We had bestowed on you. We see not with you your intercessors whom you claimed to be partners with Allah. Now all relations between you and them have been cut off, and all that you used to claim has vanished from you.

(33) Such is Allah, your Lord! La ilaha illa Huwa (none has the right to be worshipped but He), the Creator of all things. So worship Him (alone), and He is the Wakil (Trustee, Disposer of affairs, Guardian) over all things.

(34) And so We have appointed for every Prophet enemies - Shayatin (devils) among mankind and jinn, inspiring one another with adorned speech as a delusion (or by way of deception). If your Lord had so willed, they would not have done it; so leave them alone with their fabrications. (Tafsir Qurtubi)

(35) And so to many of the Mushrikun (polytheists - see V.2:105) their (Allah's so-called) "partners" have made fair-seeming the killing of their children, in order to lead them to their own destruction and cause confusion in their religion. And if Allah had willed, they would not have done so. So leave them alone with their fabrications.

(36) And they say: "What is in the bellies of such and such cattle (milk or foetus) is for our males alone, and forbidden to our females (girls and women), but if it is born dead, then all have shares therein." He will punish them for their attribution (of such false orders to Allah). Verily, He is All-Wise, All-Knower. (Tafsir At-Tabari).

(37) Say (O Muhammad صلى الله عليه وسلم): "Truly, my Lord has guided me to a Straight Path, a right religion, the religion of Ibrahim (Abraham), Hanifa [i.e. the true Islamic Monotheism - to believe in One God (Allah i.e. to worship none but Allah, alone)] and he was not of Al-Mushrikun (See V.2:105)."

(38) Alif-Lam-Mim-Sad. [These letters are one of the miracles of the Qur'an and none but Allah (alone) knows their meanings.]

(39) They said: "You have come to us that we should worship Allah alone and forsake that which our fathers used to worship. So bring us that wherewith you have threatened us if you are of the truthful."

(40) "We should have invented a lie against Allah if we returned to your religion, after Allah has rescued us from it. And it is not for us to return to it unless Allah, our Lord, should will. Our Lord comprehends all things in His Knowledge. In Allah (alone) we put our trust. Our Lord! Judge between us and our people in truth, for You are the Best of those who give judgment."
