Is Abraham Allah's son

Allah is not only the God of the Muslims. He is the God of mankind and all of his Creation. Allah means "The One God" - The Word is unchangable and is the perfect name for our Creator who himself is Perfect and Divine in his Unity.

Moses, Jesus, Muhammed and all the prophets that came before them called their people to worship the One God without any partners. They also rejected the notion that they themselves were divine figures.

Please see Quran 2:255 and 112:1-4 in order to find out how Allah presents himself to all man kind through his revelation.
