6.2.5

The springs of this lake are very deep. The first time they brought a large quantity of stone in boats and poured it on the place where now the building stands it had no result. At last they sank some thousands of boats with stones, and with great labour recovered a piece of ground 100 gaz by 100 gaz out of the water, and made a terrace, and on one side thereof the Sultan erected a temple for the worship of his supreme God. Than this there is no finer place. He often came to the spot by boat and engaged in worship of the King of Wisdom. They say he spent many "forty days" in that place. One day a wicked son of his came to that place to kill him, and finding him alone, drew a sword and went in. When his eye fell on the Sultan, however, on account of his venerable dignity and the might of his virtues, he became confused and bewildered and turned away. The Sultan shortly after came out and seated himself in the boat with this same son, and started for the city. On the way he said to his son, "I have forgotten my rosary; get into a canoe and fetch it for me." The son having gone into the temple sees his father in the same place, and the graceless man with complete shame of face falls at his father's feet and asks pardon for his fault. They have told many tales of such miracles as this of him, and they say also that he had well practised the science of khala'.
