Christian insists that Jesus was the son of God, but that he and God are one and the same. Inform the Christian: "Cows have calves; little cows. Cats have kittens; little cats. Humans have children; little humans. When God has a son, what is he? A little God? If so, you have two Gods."
"The notion that God gave birth to Himself clashes with the very essence of what it means to be God. In Islam, Allah is described as eternal and self-existent—'He begets not, nor is He begotten' (Surah Al-Ikhlas, 112:3). If God gave birth to Himself, it implies He has a beginning, a process, or a dependency, which contradicts His timeless nature. The one who creates all things cannot be subject to creation or birth—He must exist beyond such limits.
In the Trinity, saying the Son is God and was born introduces this problem: how can an eternal God be born, even to Himself? It suggests a cycle or change in God's being, which doesn't fit with absolute perfection. Tawhid resolves this: Allah is One, unchanging, and independent. He doesn't need to generate Himself because He always was and always will be. The Qur'an challenges such ideas directly: 'How can He have a child when He has no consort?' (Surah Al-An'am, 6:101). Logic and scripture align here—Allah's unity and eternity leave no room for Him giving birth, even to Himself."
The Islamic critique misunderstands the Christian concept of "Son of God" by applying a physical, creaturely analogy (cows and calves) to the infinite nature of God.
