The truest and highest stage of worship is to see God face to face, and to receive His guidance from His own mouth. Those who attain this highest stage, choose for themselves whatever God chooses for them. Their entire characters are transformed by God. They are God's friends; so they no longer discriminate between people, but regard all people as friends. Wherever they go, they go from God; wherever they arrive, they arrive at God. Whatever they do, they do for God; whatever service they perform, they perform it in God. The self has been truly annihilated.
- Junayd, "Tawhid"
