Intentionally swears falsely by a religion other than
1.
2. Narrated Thabit bin Ad-Dahhak: The Prophet (p.b.u.h) said, "Whoever
intentionally swears falsely by a religion other than Islam, then he is
what he has said, (e.g. if he says, 'If such thing is not true then I am a
Jew,' he is really a Jew). And whoever commits suicide with piece of iron
will be punished with the same piece of iron in the Hell Fire." Narrated
Jundab the Prophet said, "A man was inflicted with wounds and he
committed suicide, and so Allah said: My slave has caused death on
himself hurriedly, so I forbid Paradise for him."
