"The idea of God praying to God doesn't hold up when you consider Allah's nature in Islam. Allah is One, absolute, and self-sufficient—He has no needs, no equals, and no one above Him. The Qur'an says, 'Allah—there is no deity except Him, the Ever-Living, the Sustainer of existence' (Surah Al-Baqarah, 2:255). Prayer is an act of dependence, a creature reaching out to its Creator. If God were to pray, to whom would He pray? Himself? That suggests division or duality within God, which contradicts His perfect unity, Tawhid.
In the Trinity, Jesus (peace be upon him) prays to the Father, raising the question: if he's fully God, why does he need to pray? It implies one part of God is subordinate to another, undermining the claim of co-equality. In Islam, Allah doesn't pray—He commands, sustains, and answers prayers. He's the ultimate authority, not a being in need. Tawhid keeps it simple: God is One, beyond human acts like prayer, and that clarity reflects His unmatched power and perfection."
You have Allah praying to himself in the Qur'an for his followers (Surah 2:157, 33:43, Surah 33:56; ). So Allah is perfectly comfortable praying to himself in Islam.
In the Old Testament you have God praying to God when the angel of Yahweh (which is Yahweh himself) prays to Yahweh (Zechariah 1:12-13). This just doesn't appear to be an issue. Yes, God can pray to God. Prayer is communication. We are talking to God. Since Yahweh is a Trinity, all three persons of God can communicate with each other. They seem to talk to one another based on the bible's descriptions of how they interact (Genesis 1 "Let us" language).
When you do your dua, you expect Allah to hear you. In the same way, when Jesus was on Earth he was separate from the Father. So he prayed to him. He continued to talk to the Father when he became a human.
