And how should I fear those whom you associate in worship with Allah (though they can neither benefit nor harm), while you fear not that you have joined in worship with Allah things for which He has not sent down to you any authority. (So) which of the two parties has more right to be in security? If you but know.” [6:81]

They (Jews and Christians) took their rabbis and their monks to be their lords besides Allah (by obeying them in things which they made lawful or unlawful according to their own desires without being ordered by Allah), and (they also took as their Lord) Messiah, son of Maryam (Mary), while they (Jews and Christians) were commanded [in the Tauraat (Torah) and the Injeel (Gospel)) to worship none but One Ilaah (God – Allah) Laa ilaaha illa Huwa (none has the right to be worshipped but He). Praise and glory be to Him, (far above is He) from having the partners they associate (with Him).” [9:31]

And they worship besides Allah things that hurt them not, nor profit them, and they say: “These are our intercessors with Allah.” Say: “Do you inform Allah of what He knows not in the heavens and on the earth?” Glorified and Exalted be He above all that which they associate as partners with Him! [10:18]

Say (O Muhammad): “I am only a man like you. It has been inspired to me that your Ilah (God) is One Ilah (God i.e. Allah). So whoever hopes for the Meeting with his Lord, let him work righteousness and associate none as a partner in the worship of his Lord.” [18:110]

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 ill-Allah (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, etc.);” [22:26]

And let them not turn you (O Muhammad ) away from (preaching) the Ayat (revelations and verses) of Allah after they have been sent down to you, and invite (men) to (belief in) your Lord [i.e: in the Oneness (Tauhid) of Allah (1) Oneness of the Lordship of Allah; (2) Oneness of the worship of Allah; (3) Oneness of the Names and Qualities of Allah], and be not of the mushrikun (those who associate partners with Allah, e.g. polytheists, pagans, idolaters, those who disbelieve in the Oneness of Allah and deny the Prophethood of Messenger Muhammad). [28:87]

Allah is He Who created you, then provided food for you, then will cause you to die, then (again) He will give you life (on the Day of Resurrection). Is there any of your (so­called) partners (of Allah) that do anything of that? Glory be to Him! And Exalted be He above all that (evil) they associate (with Him). [30:40]

He is Allah than Whom there is La ilaha illa Huwa (none has the right to be worshipped but He) the King, the Holy, the One Free from all defects, the Giver of security, the Watcher over His creatures, the All-Mighty, the Compeller, the Supreme. Glory be to Allah! (High is He) above all that they associate as partners with Him. [59:23]
