"How do we purify the world?" asked a disciple.
Ibn al-Husayn replied:
"There was once a sheik in Damascus called Abu Musa al-Qumasi. Everyone honored him for his great wisdom, but no one knew whether he was a good man.
“One afternoon, a construction fault caused the house where the sheik lived with his wife, to collapse. The desperate neighbors began to dig the ruins; eventually, they managed to locate the sheik’s wife.
“She said: 'Don’t worry about me. First save my husband, who was sitting somewhere over there.'
“The neighbors removed the rubble from the area she indicated, and found the sheik. He said: 'Don’t worry about me. First save my wife, who was lying somewhere over there.'
“When someone acts as this couple did, she/he is purifying the whole world.”from Paulo Coelho
