FOUR SIGNS OF HYPOCRISY H 696 "There are four qualities which, if they are found in a person, prove him to be a real hypocrite. If a person has one of them, he has that quality of hypocrisy until he rids himself of it. They are: When he is entrusted with something he embezzles. When he speaks he lies. When he promises he breaks his promise. When he quarrels he is abusive." R 696 Bukhari and Muslim with a chain up to Abdullah, the son of Amr son of Al 'As who related that the Messenger of Allah, praise and peace be upon him, said this.
689- وعن عبد الله بن عمرو بن العاص رضي الله عنهما : أنَّ رسول الله صلى الله عليه وآله وسلم ، قَالَ : "أرْبَعٌ مَنْ كُنَّ فِيهِ كَانَ مُنَافِقاً خَالِصاً ، وَمَنْ كَانَتْ فِيهِ خَصْلَةٌ مِنْهُنَّ كَانَتْ فِيهِ خَصْلَةٌ مِنَ النِّفَاقِ حَتَّى يَدَعَهَا : إِذَا اؤْتُمِنَ خَانَ ، وَإِذَا حَدَّثَ كَذَبَ ، وَإِذَا عَاهَدَ غَدَرَ ، وَإِذَا خَاصَمَ فَجَرَ" متفقٌ عَلَيْهِ .
