Behlool (a Sufi saint who preferred to remain hidden from public hence pretended to be mad) simulated madness, though he was not mad.
Junaid a
scholar and Sufi of repute, knew him very well. One day as they met, Junaid
requested him to give him some counsel and admonition.
"You do not need
any advice. You are a well known scholar," Behlool said.
But Junaid
insisted. Behlool gave in and said: "Well, I shall ask you three questions. If
you answer them correctly, you will be advised."
And then he
proceeded to ask:
"Do you know how to talk?"
"Do you know
how to eat?"
"Do you know how to sleep?"
Junaid found these
simple. He said:
"I know how to talk. I talk with a low voice, politely
and to the point, so that the listeners are not at all offended. I eat after
having washed my hands, say Bismillah( take the name of Allah) before I commence, and chew the food
properly.
When I finish, I thank Allah. Before I go to sleep, I do my wudhu ( Muslim ritual purification with water) and
retire to a clean bed. Then I bear witness to my faith and sleep."
Behlool stood up and started walking away. He said: "I thought you were
quite learned. You do not know the most elementary things of Islam." But Junaid
would not let him go. "Please guide me," he said.
"Well," Behlool said,
"It is no use talking softly if it is a lie, remembering Allah before eating has
no meaning if the food you eat is forbidden or usurped or that the food has been
bought from the money of an orphan, a widow or a fellowman. And what is the use
of sleeping with wudhu and all the recitations if your heart is full of malice,
jealousy and enmity towards your brother in faith."
So very true , Thank you for sharing brother.
