How Is It Your Muslim Brother Is Not Safe From You?

Sufyân ibn Husayn al-Wâsitî narrates:

“I spoke ill of a person in the presence of Iyâs bin Mu’âwiyah al-Muzanî who was the judge of Basra, a Tâbi’î and a very intelligent person. He looked straight in my face and asked

Did you wage war against the Romans?’

I replied: “No”.

He asked, ‘Did you wage war against Sind, India and the Turks?’

I replied “No”

He asked ‘Did you wage war against Sind, India and the Turks?’

I replied “No”,

‘How is it then, that the Romans, the Sindis, the Indians and the Turks are safe from you whilst your own Muslim Brother is not safe from you?”

Sufyan narrates: I never did this again
