(who was one of the companions who gave the pledge of allegiance to the Prophet underneath the
tree (Al-Hudaibiya)) Allah’s Apostle said, “Whoever swears by a religion other than Islam (i.e. if
somebody swears by saying that he is a non-Muslim e.g., a Jew or a Christian, etc.) in case he is
telling a lie, he is really so if his oath is false, and a person is not bound to fulfill a vow about a thing
which he does not possess. And if somebody commits suicide with anything in this world, he will be
tortured with that very thing on the Day of Resurrection; And if somebody curses a believer, then his
sin will be as if he murdered him; And whoever accuses a believer of Kufr (disbelief), then it is as if
he killed him.”
