The word(s) "ilah" appears 128 time(s) in 105 verse(s) in Quran in Mohsin Khan translation.

(51) And (remember) Dhun-Nun (Jonah), when he went off in anger, and imagined that We shall not punish him (i.e. the calamities which had befallen him)! But he cried through the darkness (saying): La ilaha illa Anta [none has the right to be worshipped but You (O, Allah)], Glorified (and Exalted) be You [above all that (evil) they associate with You]! Truly, I have been of the wrong-doers."

(52) Say (O Muhammad صلى الله عليه وسلم): "It is revealed to me that your ilah (God) is only one ilah (God - Allah). Will you then submit to His Will (become Muslims and stop worshipping others besides Allah)?"

(53) And they are guided (in this world) unto goodly speech (i.e. La ilaha illallah, Alhamdu lillah, recitation of the Qur'an, etc.) and they are guided to the Path of Him (i.e. Allah's religion of Islamic Monotheism), Who is Worthy of all praises.

(54) And (remember) when We showed Ibrahim (Abraham) the site of the (Sacred) House (the Ka'bah at Makkah) (saying): "Associate not anything (in worship) with Me, [La ilaha illallah (none has the right to be worshipped but Allah) - Islamic Monotheism], and sanctify My House for those who circumambulate it, and those who stand up (for prayer), and those who bow (submit themselves with humility and obedience to Allah), and make prostration (in prayer);"

(55) 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),

(56) And indeed We sent Nuh (Noah) to his people, and he said: "O my people! Worship Allah! You have no other ilah (God) but Him (Islamic Monotheism). Will you not then be afraid (of Him i.e. of His punishment because of worshipping others besides Him)?"

(57) And We sent to them a Messenger from among themselves (saying): "Worship Allah! You have no other ilah (God) but Him. Will you not then be afraid (of Him i.e. of His punishment because of worshipping others besides Him)?"

(58) No son (or offspring) did Allah beget, nor is there any ilah (god) along with Him. (If there had been many gods), then each god would have taken away what he had created, and some would have tried to overcome others! Glorified be Allah above all that they attribute to Him!

(59) So Exalted be Allah, the True King: La ilaha illa Huwa (none has the right to be worshipped but He), the Lord of the Supreme Throne!

(60) And whoever invokes (or worships), besides Allah, any other ilah (god), of whom he has no proof; then his reckoning is only with his Lord. Surely! Al-Kafirun (the disbelievers in Allah and in the Oneness of Allah, polytheists, pagans, idolaters) will not be successful.
