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

(31) And to the Madyan (Midian) people (We sent) their brother Shu'aib. He said: "O my people! Worship Allah, you have no other ilah (god) but Him, and give not short measure or weight. I see you in prosperity and verily I fear for you the torment of a Day encompassing.

(32) Thus have We sent you (O Muhammad صلى الله عليه و سلم) to a community before whom other communities have passed away, in order that you might recite unto them what We have revealed to you, while they disbelieve in the Most Gracious (Allah) Say: "He is my Lord! La ilaha illa Huwa (none has the right to be worshipped but He)! In Him is my trust, and to Him will be my return with repentance."

(33) This (Qur'an) is a Message for mankind (and a clear proof against them), in order that they may be warned thereby, and that they may know that He is the only One ilah (God - Allah) - (none has the right to be worshipped but Allah) - and that men of understanding may take heed.

(34) Who set up along with Allah another ilah (god); but they will come to know.

(35) He sends down the angels with the Ruh (revelation) of His Command to whom of His slaves He wills (saying): "Warn mankind that La ilaha illa Ana (none has the right to be worshipped but I), so fear Me (by abstaining from sins and evil deeds).

(36) Your ilah (God) is One ilah (God - Allah, none has the right to be worshipped but He). But for those who believe not in the Hereafter, their hearts deny (the faith in the Oneness of Allah), and they are proud.

(37) And Allah said (O mankind!): "Take not ilahain (two gods in worship). Verily, He (Allah) is (the) only One ilah (God). Then, fear Me (Allah جل جلاله) much [and Me (Alone), i.e. be away from all kinds of sins and evil deeds that Allah has forbidden and do all that Allah has ordained and worship none but Allah] .

(38) Set not up with Allah any other ilah (god), (O man)! (This verse is addressed to Prophet Muhammad صلى الله عليه و سلم , but its implication is general to all mankind), or you will sit down reproved, forsaken (in the Hell-fire).

(39) This is (part) of Al-Hikmah (wisdom, good manners and high character) which your Lord has revealed to you (O Muhammad صلى الله عليه و سلم). And set not up with Allah any other ilah (god) lest you should be thrown into Hell, blameworthy and rejected, (from Allah's Mercy).

(40) And We have put coverings over their hearts lest they should understand it (the Qur'an), and in their ears deafness. And when you make mention of your Lord Alone [La ilaha illallah (none has the right to be worshipped but Allah) Islamic Monotheism (توحيد الله)] in the Qur'an, they turn on their backs, fleeing in extreme dislike.
