The Prophet’s heart, God bless him and give him peace, had pity for his prisoners. God most High sent down a revelation to comfort the Prophet’s heart. ‘Say to them: In your present state of bondage and chains, if you resolve to do good and be righteous God will deliver you from this. He will restore to you many times that which has been lost, many times as much. He will grant you forgiveness and pardon in the next life and the world to come. He will give you two treasures, one that has gone from you and the one in the world to come.’
-Jalal al-Din Rumi
