Sayyidina Abdullah ibn Amr (RA) reported that the Prophet (SAW) said, “If anyone has these four characteristics then he is a hypocrite and if he has one of these then he has one trait of hypocrisy till he gives it up. When he speaks, he lies; when he promises, he breaks it, when he quarrels, he abuses; and when he makes a covenant, he breaches it.”
[Ahmed 6782,Bukhari 34,Muslim 58,Abu Dawud 4688,Nisai 5030]
