An imam of Banu Sulaym narrates from his elders: They set out on a campaign against the Romans and stopped at one of their churches. There they read, written on a stone:
"Does a group that killed Husayn hope for the intercession of his grandfather on the Day of Reckoning?"
We asked them: When was this church built? They said: Three hundred years before your Prophet was sent.
