Bismillah Walhamdulillah Was Salaatu Was Salaam ‘ala Rasulillah Narrated Anas (Radi-Allahu ‘anhu):

The Prophet (Sallallahu ‘Alaihi Wa Sallam) was asked about the great sins He said, “They are:–

(1) To join others in worship with Allah,

(2) To be undutiful to one’s parents.

(3) To kill a person (which Allah has forbidden to kill) (i.e. to commit the crime of murdering).

(4) And to give a false witness.”
