Only God should be worshipped because He is the Creator and sustainer of all that exists. This Great Universe and everything that is in it cannot be the product of chance, and could not have created itself. Signs testifying that God is the only Creator can be seen throughout the earth and in the very soul of each person.

God said in the Qur’an: “It is Allah who created the sky and the earth, and sent down from the sky water by which He brought forth fruits for your sustenance. He subjected for you the ships to sail upon the sea at His command, and He subjected for you the rivers. And He subjected for you the sun and moon in continuous cycles, and He subjected for you the night and day. And He gave you all you asked Him for .” (14:32-34) 

In the Qur’an, God mentions Prophet Abraham’s search for truth as an example of how those who follow God’s signs will be rightly guided to the worship of Him alone;

God said: “In this way I showed Abraham the kingdom of the heavens and the earth so that he would have faith with understanding and certainty. When the night covered him with darkness, he saw a star and said: ‘This is my Lord’, but when it set, he said: ‘I don’t like those that set.’ When he saw the moon rising up, he said: ‘This is my Lord’, but when it set, he said: ‘Unless my Lord guides me, I will certainly be among the people who went astray.’ When he saw the sun rising up he said: ‘This is my Lord, this is the greatest of all.’ But when it set, he said: ‘O my people! I am indeed free from what you join as partners with Allah. Verily, I have turned my face towards Allah who created the heavens and the earth and I reject those who associate partners with Allah (in worship).”(6:75-79) 

Actually, in the Qur’an God calls people to continuously look at the Universe, as this will affirm the divine truth of His existence, His greatness and that He alone should be worshipped. God alone deserves our worship because only He can answer our prayers. God says in the Qur’an: “And your Lord says: Call on Me and I will answer your prayer.” (40:60) Hence, if a human being prays to an idol and his prayers are answered, it is not the idol which actually answered his 13 prayers but God. Similarly, prayers to Jesus Christ, Buddha, Krishna, Saint Christopher, Saint Jude or to Prophet Muhammad, are not answered by them, but are answered by God. Consequently, prayer is an act of worship which should be directed to God alone. Indeed, prophets who are worshipped besides Him did not tell people to worship them.

Instead, the prophets warned their people against doing just that. For example, Islam teaches that Prophet Jesus (mercy and peace of God be upon him) was a human being who was created by God in a miraculous way. He was born of a mother, Mary, without a father and he worshipped God. He was not God, nor was he the son of God. He was neither one of three manifestations of God as Christians say, nor was he the son of a prostitute as the Jews say. He told his people (the tribes of Israel) to worship God alone. He did not tell people to worship either himself or his mother. Furthermore, Prophet Jesus (mercy and peace of God be upon him) did not worship himself when he worshipped, rather he worshipped God. However, those who claim to be the followers of Jesus Christ today worship Jesus himself, claiming that he is God, and others also worship his mother calling her ‘the mother of God.’! God says in the Qur’an that He will ask Prophet Jesus (mercy and peace of God be upon him) on the Day of Judgment :

 “O Jesus, son of Mary! Did you tell people: Take me and my mother as gods besides Allah? Then he will say: Glory to you, I could never say what I had no right to say. If I had said it, You would have known it, You know what is within myself, but I do not know what is within Yourself. Verily, You alone are the Knower of the unseen. I did not say to them except what You commanded me; to worship Allah, my Lord and your Lord, and I was a witness over them as long as I was among them, but when You raised me up, You were the observer over them, and You are the witness over all things.” (5:116 – 117) 

God emphasizes in the Qur’an that Prophet Jesus (mercy and peace of God be upon him) was neither killed nor crucified, but God raised him up into the heavens in body and spirit and he will be returned to the earth before the end of the world. Prophet Muhammad (mercy and peace of God be upon him) stated that Prophet Jesus would rule the earth according to the Islamic law, then he will die on earth like other human beings and will be buried and resurrected like them on the Day of Judgment. Hence, Prophet Jesus who was given life, was born from a woman’s womb and circumcised, ate, slept, went to the toilet, grew up, prayed, and will die, should never be taken as God as all these characteristics are not the attributes of God, but of His creatures.

The New Testament states that Jesus Christ taught his followers to pray to God saying: “Our Father6 who art in heaven, hallowed be your name, your kingdom come, your will be done on earth as it is in heaven.” (Luke 11:2 / Matthew 6:9-10) Also, he taught that only those who submit to God would inherit paradise: “None of those who call me ‘Lord’ will enter the Kingdom of God, except one who does the will of my Father in heaven.”(Matthew 7:21)

Prophet Jesus also pointed out that he himself submitted to the will of God: “I cannot do anything of myself. I judge as I hear and my judgment is honest because I am not seeking my own will but the will of Him who sent me.” (John 5:23) In fact, there are many reports in the Gospels that show that Prophet Jesus made it clear to his followers that he was not God. For example, when speaking about the final hour, he said: “No one knows about that day or hour, not even the angels in heaven, not the Son7, but only the Father.”
