In the Name of God, the Merciful, the Compassionate.
Those who believe in the Unseen1
If you want to understand what great happiness and bounty, what great pleasure and ease are to be found in belief in God, listen to this story which is in the form of a comparison:
One time, two men went on a journey for both pleasure and business. One set off in a selfish, inauspicious direction, and the other on a godly, propitious way.
Since the selfish man was both conceited, self-centred, and pessimistic, he ended up in what seemed to him to be a most wicked country due to his pessimism. He looked around and everywhere saw the powerless and the unfortunate lamenting in the grasp of fearsome bullying tyrants, weeping at their destruction. He saw the same grievous, painful situation in all the places he travelled. The whole country took on the form of a house of mourning. Apart from becoming drunk, he could find no way of not noticing this grievous and sombre situation. For everyone seemed to him to be an enemy and foreign. And all around he saw horrible corpses and despairing, weeping orphans. His conscience was in a state of torment.
The other man was godly, devout, fair-minded, and with fine morals so that the country he came to was most excellent in his view. This good man saw universal rejoicing in the land he had entered. Everywhere was a joyful festival, a place for the remembrance of God overflowing with rapture and happiness; everyone seemed to him a friend and relation. Throughout the country he saw the festive celebrations of a general discharge from duties accompanied by cries of good wishes and thanks. He also heard the sound of a drum and band for the enlistment of soldiers with happy calls of "God is Most Great!" and "There is no god but God!" Rather than being grieved at the suffering of both himself and all the people like the first miserable man, this fortunate man was pleased and happy at both his own joy and that of all the inhabitants. Furthermore, he was able to do some profitable trade. He offered thanks to God.
