Bismillah Walhamdulillah Was Salaatu Was Salaam ‘ala Rasulillah
Narrated by Thabit bin Ad-Dahhak (Radi-Allahu ‘anhu):
(who
was one of the companions who gave the pledge of allegiance to the
Prophet (Sallallahu ‘Alaihi Wa Sallam) underneath the tree
(Al-Hudaibiya))
Allah’s Apostle (Sallallahu ‘Alaihi Wa Sallam)
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.), if his oath is false, he is really so. 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.”
