They say: "Become Jews or Christians if ye would be guided (To salvation)." Say thou: "Nay! (I would rather) the Religion of Abraham the True, and he joined not gods with Allah." (Quran 2:135)

Say: "O People of the Book! come to common terms as between us and you: That we worship none but Allah; that we associate no partners with him; that we erect not, from among ourselves, Lords and patrons other than Allah." If then they turn back, say ye: "Bear witness that we (at least) are Muslims (bowing to Allah's Will). (Quran 3:64)

No matter what religion is concerned if it becomes institutional, man like Pope, Priesthood, Rabbinate (among the Jews it was hereditary also) or Brahman will direct it and God remains behind. The original Islamic teaching calls everybody to leave differences created by men and come to the common terms what we accept as a whole. Why should war start between us based only the menmade manipulations in the name of religion while the essence of the faith is the same? The original Islamic principles are teachings for the unification.

Abraham was not a Jew nor yet a Christian; but he was true in Faith, and bowed his will to Allah's (Which is Islam), and he joined not gods with Allah. (Quran 3:67)

Whether Abraham, Ismael and Isaac were Jew or Christian? What a question! Judaism started much later with the mission of Moses. Before Moses there were no concept to refer to as Jewish. House of Israel began with Jacob even after Moses. Who is Jew than? Only those are Jews who consider themselves Jew after the revelations came for Moses or after the establishment of House of Israel. Abraham was born much before Moses in Ur, Chaldea what is in the today Iraq. Based on the human logic every Iraqi can claim him as Iraqi.

They do blaspheme who say: "(Allah) is Christ the son of Mary." But said Christ: "O Children of Israel! worship Allah, my Lord and your Lord." Whoever joins other gods with Allah,- Allah will forbid him the garden, and the Fire will be his abode. There will for the wrong-doers be no one to help. (Quran 5:72)

Matt. 4:10, where Christ rebukes Satan for desiring the worship of other than Allah: John 20:17, where Christ says to Mary Magdalene, "Go unto my brethren, and say unto them, I ascend unto my Father and your Father; and to my God and your God.” Also Luke 18:19, where Christ rebukes a certain ruler for calling him Good Master: "Why callest thou me good? None is good, save One, that is, Allah." In Mark 12:29 Jesus says: "The first of all the commandments is, Hear 0 Israel; the Lord our God is One Lord."

Since ancient Egypt clergy played intermediator role between heaven and earthly mortal beings. In order to keep this position, they applied mysterious, theatrical means to convince audience about their unique skill as interpreters of the divine phenomenon. Later Judaism and Christianity also suffered from the same activity of some priests. For being credible the clergy itself created the mystic elements. Faith what was taught by Prophets as it is a direct link between humans and their Creator in order to liberate them from the firm dogmas which were manipulated by their previous priesthood. However, mankind fell again into the trap of spiritual slavery time to time. God has never accepted that situation therefore Shirk is main sin.

"And behold! ye come to us bare and alone as We created you for the first time: ye have left behind you all (the favours) which We bestowed on you: We see not with you your intercessors whom ye thought to be partners in your affairs: so now all relations between you have been cut off, and your (pet) fancies have left you in the lurch!" (Quran 6:94)

Some of the various ideas connected with "creation" are noted in 2:117. In the matter of creation of man there are various processes. If his body was created out of clay, i.e. earthy matter, there was an earlier process of the creation of such earthy matter. Here the body is left behind, and the soul is being addressed. The soul underwent various processes of fashioning and adapting to its various functions in its various surroundings (32:7-9). But each individual soul, after release from the body, comes back as it was created, with nothing more than its history, "the deeds which it has earned," which are really a part of it. Any exterior things given to help in its development, "the favors which we bestowed on you," it must necessarily leave behind; however, it may have been proud of them. These exterior things may be material things, e.g. wealth, property, signs of power, influence and pride such as sons, relatives, and friends, etc., or they may be intangible things, like talents, intellect, social gifts, etc.

Persons, conceptions, principles and objects which have got distinguished role while were adored as idols in the earthly life, after death they disappear immediately. In the Hereafter they have no role. Only the spirit reckons in the same state as it arrived to the earthly life. This is the real value and credit of idols.

Say: the things that my Lord hath indeed forbidden are: shameful deeds, whether open or secret; sins and trespasses against truth or reason; assigning of partners to Allah, for which He hath given no authority; and saying things about Allah of which ye have no knowledge. (Quran 7:33)

The Jews call 'Uzair a son of Allah, and the Christians call Christ the son of Allah. That is a saying from their mouth; (in this) they but imitate what the unbelievers of old used to say. Allah's curse be on them: how they are deluded away from the Truth! (Quran 9:30)

In 5:18, I have quoted passages from the Old Testament, showing how freely the expression "sons of Allah" was used by the Jews. A sect of them called 'Uzair a son of Allah, according to Baidhawl. In Appendix II (Surah 5) I have shown that the constitution of Judaism dates from 'Uzair (Ezra). The Christians still call Christ the Son of God.

Taking men for gods or sons of Allah was not a new thing. All ancient mythologies have fables of that kind. There was less excuse for such blasphemies after the Prophets of Allah had clearly explained out true relation to Allah than in the times of primitive ignorance and superstition.

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 Allah. there is no god but He. Praise and glory to Him: (Far is He) from having the partners they associate (with Him). (Quran 9:31)

Priest worship, and the worship of saints and ascetics is a form of superstition to which men have been prone in all ages. The growth of Jewish superstition is shown in the Talmud, and of Christian superstition in the doctrine of papal infallibility and the worship of saints. The mere idea of a separate order of priesthood to stand between Allah and man and be the exclusive repository of Allah's secrets is derogatory to the goodness and all-pervading grace of Allah.

It is He Who hath sent His Messenger with guidance and the Religion of Truth, to proclaim it over all religion, even though the Pagans may detest (it). (Quran 9:33)

Every religion which commends itself widely to human beings and lasts through some space of time has a glimpse of Truth in it. But Islam being the perfect light of Truth is bound to prevail. See also 48:28 and 61:9

O ye who believe! there are indeed many among the priests and anchorites, who in Falsehood devour the substance of men and hinder (them) from the way of Allah. And there are those who bury gold and silver and spend it not in the way of Allah. announce unto them a most grievous penalty- (Quran 9:34)

This was strikingly exemplified in the history of Mediaeval Europe. Though the disease is apt to attack all peoples and organizations at all times. Priests got rich by issuing indulgences and dispensations; they made their office a stepping stone to worldly power and possessions.

Say: "I am but a man like yourselves, (but) the inspiration has come to me, that your Allah is one Allah. whoever expects to meet his Lord, let him work righteousness, and, in the worship of his Lord, admit no one as partner. (Quran 18:110.)

Righteousness and true respect for Allah; which excludes the worship of anything else, - whether idols, or deified men, - or forces of nature, - or faculties of man, - or Self. These are the criteria of true worship.

It is Allah Who has created you: further, He has provided for your sustenance; then He will cause you to die; and again He will give you life. Are there any of your (false) "Partners" who can do any single one of these things? Glory to Him! and high is He above the partners they attribute (to him)! (Quran 30:40)

The persons or things or ideas to which we give part-worship, while our whole and exclusive worship is due to Allah, are the "Partners" we set up. Do we owe our existence to them? Do they sustain our being? Can they take our life or give it back to us? Certainly not. Then how foolish of us to give them part-worship!

The same religion has He established for you as that which He enjoined on Noah - the which We have sent by inspiration to thee - and that which We enjoined on Abraham, Moses, and Jesus: Namely, that ye should remain steadfast in religion, and make no divisions therein: to those who worship other things than Allah, hard is the (way) to which thou callest them. Allah chooses to Himself those whom He pleases, and guides to Himself those who turn (to Him). (Quran 42:13)

Allah's Religion is the same in essence, whether given, for example, to Noah, Abraham, Moses, or Jesus, or to our holy Prophet. The source of unity is the revelation from Allah. In Islam it is "established" as an institution, and does not remain merely a vague suggestion. Faith, Duty or Religion, is not a matter to dispute about. The formation of sects is against the very principle of Religion and Unity. What we should strive for is steadfastness in duty and faith, and unity among mankind.

And that He may punish the Hypocrites, men and women, and the Polytheists men and women, who imagine an evil opinion of Allah. On them is a round of Evil: the Wrath of Allah is on them: He has cursed them and got Hell ready for them: and evil is it for a destination. (Quran 48:6)

Associating partners, rivals to God (Shirk) is forbidden in every Monotheist religions. Shirk has two main groups: 1. Religious, 2. Secular. The purpose is in both cases the acquisition of power while souls are perished and humans are subjugated. Legislation and jurisdiction if serve Shirk have to be considered as sinner.
