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

(81) Lord of the heavens and the earth, and all that is between them, so worship Him (alone) and be constant and patient in His worship. Do you know of any who is similar to Him? (of course none is similar or co-equal or comparable to Him, and He has none as partner with Him). [There is nothing like Him and He is the All-Hearer, the All-Seer].

(82) And We shall inherit from him (at his death) all that he talks of (i.e. wealth and children which We have bestowed upon him in this world), and he shall come to Us alone.

(83) And everyone of them will come to Him alone on the Day of Resurrection (without any helper, or protector or defender).

(84) Ta-Ha. [These letters are one of the miracles of the Qur'an, and none but Allah (alone) knows their meanings].

(85) Musa (Moses) said: "Then go away! And verily, your (punishment) in this life will be that you will say: "Touch me not (i.e. you will live alone exiled away from mankind); and verily (for a future torment), you have a promise that will not fail. And look at your ilah (god) to which you have been devoted. We will certainly burn it, and scatter its particles in the sea."

(86) And We did not send any Messenger before you (O Muhammad صلى الله عليه وسلم) but We revealed to him (saying): La ilaha illa Ana [none has the right to be worshipped but I (Allah)], so worship Me (alone and none else)."

(87) And We made them leaders, guiding (mankind) by Our Command, and We revealed to them the doing of good deeds, performing Salat (Iqamat-as-Salat), and the giving of Zakat and of Us (alone) they were the worshippers.

(88) Truly! This, your Ummah [Shari'ah or religion (Islamic Monotheism)] is one religion, and I am your Lord, therefore worship Me (alone). [Tafsir Ibn Kathir]

(89) And for every nation We have appointed religious ceremonies, that they may mention the Name of Allah over the beast of cattle that He has given them for food. And your Ilah (God) is One Ilah (God - Allah), so you must submit to Him alone (in Islam). And (O Muhammad صلى الله عليه وسلم) give glad tidings to the Mukhbitun (those who obey Allah with humility and are humble from among the true believers of Islamic Monotheism),

(90) Or say they: There is madness in him? Nay, but he brought them the truth [i.e. Tauhid: Worshipping Allah alone in all aspects, the Qur'an and the religion of Islam], but most of them (the disbelievers) are averse to the truth.
