Imam Ali [a] bought Maytham from a woman belonged to Bani Asad. The Imam asked Maytham:
What's your name?
The Imam said:
Allah Apostle [s] has told me that the Iranians call you Maytham.
Maytham was astonished because no one knew his real name. So, he said:
Allah and His Apostle are truthful.
Since that day, Maytham had not left the Imam.
