Volume 8, Book 78, Number 647:
Narrated Thabit bin Ad-Dahhak:
The Prophet said, “Whoever swears by a religion other than Islam, is, as he says; and whoever
commits suicide with something, will be punished with the same thing in the (Hell) Fire; and cursing
a believer is like murdering him; and whoever accuses a believer of disbelief, then it is as if he had
killed him.”
