عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو رَضِيَ اللَّهُ عَنْهُمَا قَالَ قَالَ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ ((ثَلَاثٌ إِذَا كُنَّ فِي الرَّجُلِ فَهُوَ الْمُنَافِقُ الْخَالِصُ إِنْ حَدَّثَ كَذَبَ وَإِنْ وَعَدَ أَخْلَفَ وَإِنِ ائْتُمِنَ خَانَ وَمَنْ كَانَتْ فِيهِ خَصْلَةٌ مِنْهُنَّ لَمْ يَزَلْ يَعْنِي فِيهِ خَصْلَةٌ مِنَ النِّفَاقِ حَتَّى يَدَعَهَا))
It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: There are three traits; whoever possesses them is a pure hypocrite: when he speaks, he lies; when he makes a promise, he breaks it; and when he is entrusted, he betrays the trust. And whoever has one of these traits in him, then he has a trait of hypocrisy in him until he abandons it.
