It is narrated on the authority of Abdullah b. 'Amr that the Prophet observed:
"There are four characteristics, whoever has them all is a pure hypocrite, and whoever has one of its characteristics, he has one of the characteristics of hypocrisy, until he gives it up: When he speaks he lies, when he makes a covenant he betrays it, when he makes a promise he breaks it, and when he disputes he resorts to obscene speech."
In the narration of Sufyan (one of the narrators) it is: "And if he has one of them, he has one of the characteristics of hypocrisy."
It is reported on the authority of Abu Huraira that the Messenger of Allah (may peace and blessings be upon him) said:
Three are the signs of a hypocrite: when he spoke he told a lie, when he made a promise he acted treacherously against it, when he was trusted he betrayed.
It is reported on the authority of Abu Dharr that he heard the Messenger of Allah (may peace and blessings be upon him) saying:
No person who claimed knowingly anyone else as his father besides (his own) committed nothing but infidelity, and he who made a claim of anything, which (in fact) did not belong to him, is not amongst us; he should make his abode in Fire, and he who labeled anyone with unbelief or called him the enemy of Allah, and he was in fact not so, it rebounded on him.

Upon this the woman remarked: What is wrong with our common sense and with religion? He (the Holy Prophet) observed: Your lack of common sense (can be well judged from the fact) that the evidence of two women is equal to one man, that is a proof of the lack of common sense, and you spend some nights (and days) in which you do not offer prayer and in the month of Ramadan (during the days) you do not observe fast, that is a failing in religion.
