The True Message of Isa AS: Pure Tawhid

When Allah sent Isa ibn Maryam (peace be upon him) to the Children of Israel, his message was unmistakably clear: worship Allah alone, with no partners, no intermediaries, and no rivals. The Quran preserves this original call in its purest form, stating what Isa himself declared: "Indeed, I am the servant of Allah. He has given me the scripture and made me a prophet" (Surah Maryam 19:30). The opening word of his first utterance — "servant" — establishes with absolute clarity the nature of Isa AS: a human being, created and sent by his Creator, with no share in divinity. Isa عليه السلام came at a time when the religion of the Israelites had become distorted through centuries of deviation. The scholars of his day — the Pharisees and temple priests — had buried the essence of monotheism under layers of ritual formalism, nationalist exclusivity, and love of worldly status. Isa cut through this with a message of direct servitude to Allah, sincere internal worship, and radical moral reform. The Quran records his mission: "And [Isa will be] a messenger to the Children of Israel, [who will say]: 'Indeed I have come to you with a sign from your Lord'" (Surah Aal Imran 3:49). The Injil (Gospel) that was revealed to Isa AS was genuine divine revelation — a confirmation and partial modification of the Torah, purifying the excesses that had accumulated and calling humanity back to the fitrah. It contained guidance on prayer, fasting, purification of the heart, care for the poor, and the remembrance of death. Its core message was the same as every prophet before him: la ilaha illa Allah — there is no god but Allah. Isa AS explicitly rejected any claim to divinity. The Quran narrates a future scene on the Day of Judgment in which Allah asks: "O Isa, son of Maryam, did you say to the people: 'Take me and my mother as deities besides Allah?'" and Isa responds: "Exalted are You! It was not for me to say that to which I have no right. If I had said it, You would have known it" (Surah Al-Ma'idah 5:116). This is the definitive Quranic testimony: the claim of Isa's divinity is a human fabrication, one he himself will disown before Allah. The concept of the Trinity — Father, Son, and Holy Spirit as co-equal and co-eternal — has no basis in the original message of Isa AS. The Quran states plainly: "They have certainly disbelieved who say, 'Allah is the third of three.' And there is no god except one God" (Surah Al-Ma'idah 5:73). Tawhid — absolute, undivided monotheism — was the foundation of his call, as it was the foundation of every prophet's call from Adam to Muhammad ﷺ. Isa AS also gave explicit glad tidings of a messenger to come after him. The Quran records this prophecy: "And [mention] when Isa, the son of Maryam, said: 'O Children of Israel, indeed I am the messenger of Allah to you confirming what came before me of the Torah and bringing good tidings of a messenger to come after me, whose name is Ahmad'" (Surah As-Saff 61:6). This prophecy — pointing toward the Prophet Muhammad ﷺ — was a foundational element of the true Injil, one that those who corrupted the message would work hard to obscure or reinterpret.
