M4:3509 — شربتی خوردم ز الله اشتری / تا به محشر تشنگی ناید مرا

This couplet is spoken by the Copt who, having witnessed the miracles and spiritual power of the Israelite Prophet (Sibti), has converted to the true faith. He is expressing the profound spiritual satisfaction he has found. The 'draught' he drank is not a physical liquid but a metaphor for the deep spiritual experience and knowledge he has gained through faith and the Prophet's guidance. The phrase "God is the Buyer" (الله اشتری) is an allusion to Quran 9:111, which speaks of God buying the souls and wealth of believers in exchange for Paradise. By connecting his spiritual drink to this Quranic verse, the Copt implies that he has entered into this divine transaction, surrendering himself to God and receiving an eternal reward – in this case, the quenching of all spiritual thirst. This experience is so complete and transformative that he believes he will never again feel the pangs of spiritual longing or doubt, even when facing the ultimate reality of the Resurrection.
