The Prophetic Blueprint: God's greatest favor is the mission of self-purification and teaching.
This confirms the sending of the Messenger as the fulfillment of Abraham's prayer and God's greatest favor. The mission is a 4-step blueprint: recitation, **purification** (*tazkiyah*), teaching the Book, and imparting wisdom/new knowledge. Prioritize heart-purification (sincerity, humility) before deep scholarly study, recognizing it is the prerequisite for beneficial knowledge and transformation.
