The passage describes a response from Sa'd ibn Abi Waqqas to Rustam. Sa'd's letter is characterized by a blend of firmness and gentleness. He speaks of God, Muhammad, and the path of truth. He mentions jinn, Adam, the lineage of the Prophet, wine, the Holy Quran, monotheism, promises and threats, the river of milk, the tree of purity, the Hour, Hell, and the praise of Muhammad. If the Shah accepts this religion, he will attain happiness.
