Excerpt from 'Salman al-Muhammadi':
[In the Prophet's Mosque]
The Muslims came together in the Prophet's Mosque. They were thanking Allah, the Glorified. They were looking at Salman, the great companion, with love and respect because he saved Madina and Islam from the invaders with his plan.
For this reason, the Ansar from Madina said:
Salman is one of us!
And the Muhajireen shouted:
Salman is one of us!
And the Muslims listened to the Prophet [s] to hear his view about Salman:
Salman is a member of my family!
Then the Prophet [s] said:
Don't say Salman al-Farsi, but say Salman al-Muhammadi!
Since that day, the Muslims had looked gratefully and respectfully at Salman.
