One of the kings of Persia sent a skilled physician to serve Muhammad, peace and blessings be upon him.

He stayed in the land of Arabia for a year, and no one sought his medical expertise or requested treatment from him.

He came to the Prophet and complained: 'This servant has been sent to treat the companions, and during this time no one paid attention so that I could perform the service assigned to me.'

The Prophet, peace be upon him, said: 'These people have a way that they do not eat until hunger overcomes them, and they stop eating while they still have an appetite.'

The physician said: 'This is the cause of good health.'

He kissed the ground and left.

A wise man begins to speak only when

Or extends his finger towards food

When silence would cause harm

Or abstaining from food would endanger his life

Therefore, his speech is wisdom

And his eating brings health
