Purity in things is a principle, and impurity is an incidental matter, so we are with the principle unless that incident occurs, and this is our doctrine. The servant is essentially pure in his servitude because he was created on the nature, which is acknowledgment of servitude to the Lord, Glory be to Him. God Almighty said, “And when your Lord took from the children of Adam from their backs their offspring.” And let them bear witness against themselves. Am I not your Lord? They said, Yes.

The Messenger of God, may God bless him and grant him peace, said in this verse that when God created Adam, He seized his back and extracted from him something like an atom, so they made them bear witness against themselves .
