It has been observed that many people and even some translators of the Arabic Quran into English made an oversight over the application of the word “Allah” and that of “ilah”. The common error is that they equate the meaning of the Arabic Allah is the same as ‘ilah” to mean God. However, Allah is the name of the God of Islam while “ilah” is the Arabic word meaning God. Allah has been the name of God coming from the compound Arabic word Al-ilah which means The God, and is derived from al (the) ilah (deity). The Arabic name for “God” is the word “Al-ilah”. With the definite article “The” or “Al” it is considered the Highest God. Allah had been the God worshipped by the Arab during Prophet Muhammad’s time and also prior of him before he was made the messenger. Nevertheless, the multiple of gods and goddesses to the Arab served specific purpose and apart from that they made those gods partners to the Highest God Allah. It was then the duty of the messenger to propagate to his community to serve and worship only One God Allah as stated in Surah 38:4-7 So they wonder that a Warner has come to them from among themselves! and the Unbelievers say, “This is a sorcerer telling lies! “Has he made the gods (all) into one Allah. Truly this is a wonderful thing!” And the leader among them go away (impatiently), (saying), “Walk ye away, and remain constant to your gods! For this is truly a thing designed (against you)! “We never heard (the like) of this among the people of these latter days: this is nothing but a made-up tale!”
The verses below confirmed that Allah is a name
>>>>>Surah 1:1-4 In the name of Allah, Most Gracious, Most Merciful. 2. Praise be to Allah, the Cherisher and Sustainer of the worlds; Most Gracious, Most Merciful; Master of the Day of Judgment.
>>>>>Surah 17:110-111 Say: “Call upon Allah, or call upon Ar Rahman: by whatever name ye call upon Him, (it is well): for to Him belong the Most Beautiful Names. Neither speak thy Prayer aloud, nor speak it in a low tone, but seek a middle course between.” And Say: “Praise be to Allah, who begets no son, and has no partner in (His) dominion: Nor (needs) He any to protect Him from humiliation: yea, magnify Him for His greatness and glory!”
>>>>>Surah 7:180 The most beautiful names belong to Allah: so, call on him by them; but shun such men as use profanity in his names: for what they do, they will soon be requited.
The verses below will show the difference between a name of God Allah and word meaning God “ilah”

Christ Jesus the son of Mary was (no more than) a messenger of Allah, and His Word, which He bestowed on Mary, and a spirit proceeding from Him: so, believe in Allah and His messengers. Say not “Trinity”: desist: it will be better for you: for Allah is One God (ilahun wahidun): Glory be to Him: (far exalted is He) above having a son. To Him belong all things in the heavens and on earth. And enough is Allah as a Disposer of affairs.
>>>>>Surah 9:31 They take their priests and their anchorites to be their lords in derogation of Allah, and (they take as their Lord) Christ the son of Mary; yet they were commanded to worship but One God (ilahan wahidan): there is no god (ilah) but He. Praise and glory to Him: (Far is He) from having the partners they associate (with Him).
>>>>>Surah 11:14 “If then they (your false gods) answer not your (call), know ye that this revelation is sent down (replete) with the knowledge of Allah, and that there is no god (ilah) but He! will ye even then submit (to Islam)?”
>>>>>Surah 13:30 Thus have we sent thee among a People before whom (long since) have (other) Peoples (gone and) passed away; in order that thou might rehearse unto them what We send down unto thee by inspiration; yet do they reject (Him), the Most Gracious! Say: “He is my Lord! There is no god (ilah) but He! On Him is my trust, and to Him do I turn!”
>>>>>Surah 14:52 Here is a Message for mankind: Let them take warning therefrom, and let them know that He is (no other than) One God (ilahun wahidun): let men of understanding take heed.

>>>>>Surah 20:98 But your God (ilahukum) is Allah: there is no god (ilah) but He: all things He comprehends in His knowledge.
>>>>>Surah 21:25 Not a messenger did We send before thee without this inspiration sent by Us to him: that there is no god (ilah) but I; therefore, worship Me.
>>>>>Surah 21:87 And remember Zun-nun, when he departed in wrath: He imagined that We had no power over him! But he cried through the depths of darkness, “There is no god (ilah) but thou: glory to thee: I was indeed wrong!”
>>>>>Surah 21:108 Say: “What has come to me by inspiration is that your God (ilahukum) is One God (ilahun wahidun): will ye therefore bow to His Will (in Islam)?”
>>>>>Surah 27:26 “Allah! There is no god (ilah) but He! Lord of the Throne Supreme!”
>>>>>Surah 28:70 And He is Allah: There is no god (ilah) but He. To Him be praise, at the first and at the last: for Him is the Command, and to Him shall ye be brought back.
>>>>>Surah 28:88 And call not, besides Allah, on another god (ilahan). There is no god (ilah) but He. Everything (that exists) will perish except His own Presence. To Him belongs the Command, and to Him will ye be brought back.
>>>>>Surah 37:4 Verily, verily, your God (ilahukum) is one!
>>>>>Surah 37:35 For they, when they were told that there is no god (ilah) except Allah, would puff themselves up with Pride,
>>>>>Surah 38:65 Say: “Truly am I a Warner: no god (ilahin) is there but the Allah, the One and Irresistible.
>>>>>Surah 40:16 The Day whereon they will (all) come forth: not a single thing concerning them is hidden from Allah. Whose will be the dominion that Day?” That of Allah, the One the Irresistible!
>>>>>Surah 40:84 But when they saw Our Punishment, they said: “We believe in Allah, the one and only and we reject the partners we used to join with Him.”
>>>>>Surah 44:8 There is no god (ilah) but He: It is He Who gives life and gives death, The Lord and Cherisher to you and your earliest ancestors.
>>>>>Surah 73:9 (He is) Lord of the East and the West: there is no god (ilah) but He: take Him therefore for (thy) Disposer of Affairs.
It is therefore an error when one speaks and make reference that “There is no god but God” It is always “There is no god but Allah”.
