When the Sultan heard how wicked his older sons had been his grief for their death was assuaged.
"Allah be praised," he said, "that I have at least one son who is worthy!"
After the betrothal ceremony the Sultan and the Youngest Prince went to the mosque to pray. While they prayed the Nightingale sang so gloriously that it seemed to them they were no longer on earth but in Paradise.
When their prayers were finished and they were passing out, the Dervish raised his sing-song voice and said:
"Now indeed is the Sultan's Mosque the most beautiful Mosque in the World for the Nightingale Gisar sings beside the Fountain!"
