Theologically speaking, the universality of the Prophet Muhammad’s message, peace and blessings be upon him, comes from the concept of one God who is the God of all, not only the God of Muslims. God describes Himself in the first chapter of the Qur’an, which is recited by all Muslims around the world in their five daily prayers; He is the God of all creation, “Rabb al-Alamīn.” Whether humans are aware of this fact or not, God is the God of all mankind—Muslims, Christians, atheists, etc.—regardless of their differences. God is the creator of everything, with no exception. The Qur’an declares that a gigantic star and an atom are shoulder to shoulder, worshipping the same God; a fly and an elephant are brothers and sisters; all of creation is here to help us understand the meaning and the mystery of the universe.
All praises and thanks, be to Almighty God, the creator of all that exists. The greatest thing that God has offered humanity is that he provided them messengers chosen from among the best of their kind.
He disclosed and conferred upon man the Revelation to guide everyone towards the truth, the straight path, as well as warn and deliver people from falsehood and evil, such that they would alone seek His pleasure and satisfaction in pursuit of Paradise.
Since time immemorial, God sent prophets after prophets, messages after messages --- dating from Noah to Abraham, Moses, Jesus (Peace be upon all of them) and culminating with the seal of them all, Muhammad (Peace be upon him), who came to confirm not only the previous messengers but especially that of the universal message which calls people to worship the Creator alone.
The Apostle believeth in what hath been revealed to him from his Lord, as do the men of faith. Each one (of them) believeth in God, His angels, His books, and His apostles. "We make no distinction (they say) between one and another of His apostles." And they say: "We hear, and we obey: (We seek) Thy forgiveness, our Lord, and to Thee is the end of all journeys." (Al-Quran 2:285)
And (remember) Abraham when he said to his people: "Worship Allah (Alone), and fear Him: that is better for you if you know and understand.(Al-Ankabut:16)
And Moses said: "O my people! If you do really believe in Allah, then put your trust in Him if you are Muslims (those who submit to Allah's Will)."(Yunus:84)
Surely, they have disbelieved who say: "Allah is the Messiah son of Mary." But the Messiah said: "O Children of Israel! Worship Allah, my Lord and your Lord." Verily, whosoever sets up partners (in worship) with Allah, then Allah has forbidden Paradise to him, and the Fire will be his abode . And for the Zalimun (polytheists and wrong-doers) there are no helpers.(Al-Maidah:72)
“ Say ( O Muhammad ) : ‘ He is Allah , the One. Allah, the eternally besought of all. He begets not nor was He begotten. And there is none co-equal or comparable unto Him”. (Al-Ikhlas:1-4)
