‘Abd Allah b. ‘Amr reported the Messenger of Allah (May peace be upon him) as saying:Four characteristics constitute anyone who possesses them a sheer hypocrite, and anyone who possesses one of them possesses a characteristics of hypocrisy till he abandons it : when he talks he lies, when he makes a promise he violates it, when he makes a covenant he acts treacherously, and when he quarrels, he deviates from the Truth.
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ نُمَيْرٍ، حَدَّثَنَا الأَعْمَشُ، عَنْ عَبْدِ اللَّهِ بْنِ مُرَّةَ، عَنْ مَسْرُوقٍ، عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " أَرْبَعٌ مَنْ كُنَّ فِيهِ فَهُوَ مُنَافِقٌ خَالِصٌ وَمَنْ كَانَتْ فِيهِ خَلَّةٌ مِنْهُنَّ كَانَ فِيهِ خَلَّةٌ مِنْ نِفَاقٍ حَتَّى يَدَعَهَا إِذَا حَدَّثَ كَذَبَ وَإِذَا وَعَدَ أَخْلَفَ وَإِذَا عَاهَدَ غَدَرَ وَإِذَا خَاصَمَ فَجَرَ " .
