It was narrated from ‘Abdullah bin ‘Amr that the Prophet صلی اللہ علیہ وآلہ وسلم said: “There are four (traits), whoever has them is a hypocrite and whoever has one of them, then has one of the traits of hypocrisy until he gives it up: When he speaks, he lies; when he makes a promise, he breaks it; when he makes a covenant, he betrays it; and when he argues, he resorts to foul language.” (Sahih)
