Is it permissible to say that we are all children of God because we return to Him in worship and He created us all, as Dr. Zakir Naik mentioned in the context of his rebuttal to the statement "Christ is the son of God"?

The context in which these words were spoken must be taken into consideration. When refuting disbelievers, atheists, and people of innovation and misguided desires, the style of argumentation and compelling evidence is employed, as opposed to the context of initially establishing a creed. By way of compelling evidence, it is said to Christians: The Bible uses the terms "fatherhood" and "sonship" metaphorically, and Jesus says about God: "My Father and your Father." The scholar Muhammad Rahmatullah Al-Hindi compellingly argued against Christians in his book "Izhar al-Haqq" using Christ's words to Mary Magdalene in the Gospel of John: "(Do not cling to me, for I have not yet ascended to my Father; but go to my brothers and say to them, 'I am ascending to my Father and your Father, and to my God and your God.')" In this, he equated himself with people, thereby declaring that he is a servant of God. This corresponds to what God narrated about him in the Qur'an: {I did not tell them anything except what You commanded me: worship Allah, my Lord and your Lord.}
