Mukhtasar Muslim

Narrated Abdullah bin Amr, may Allah be pleased with them, that the Messenger of Allah, peace and blessings be upon him, said: "Whoever possesses four traits is a pure hypocrite. And whoever has one of these traits has a characteristic of hypocrisy until he gives it up: When he speaks, he lies; when he makes an agreement, he acts treacherously; when he makes a promise, he breaks it; and when he quarrels, he behaves in a very imprudent, insulting manner or abuses. And in Sufyan's narration, the word 'khalah' is replaced with 'khaslah'."

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: There are three signs of a hypocrite: when he speaks, he lies; when he makes a promise, he breaks it; and when he is entrusted with something, he betrays the trust.
