Sunan an-Nasa'i 5020
It was narrated from 'Abdullah bin 'Amr that:
The Prophet [SAW] said: "There are four (traits), whoever has them is a hypocrite and whoever has one of them, then has one of the traits of hypocrisy, until he gives it up: When he speaks, he lies; when he makes a promise, he breaks it; when he makes a covenant, he betrays it; and when he argues, he resorts to foul language."
أَخْبَرَنَا بِشْرُ بْنُ خَالِدٍ قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ عَنْ شُعْبَةَ عَنْ سُلَيْمَانَ عَنْ عَبْدِ اللَّهِ بْنِ مُرَّةَ عَنْ مَسْرُوقٍ عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو  عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ أَرْبَعَةٌ مَنْ كُنَّ فِيهِ كَانَ مُنَافِقًا أَوْ كَانَتْ فِيهِ خَصْلَةٌ مِنْ الْأَرْبَعِ كَانَتْ فِيهِ خَصْلَةٌ مِنْ النِّفَاقِ حَتَّى يَدَعَهَا إِذَا حَدَّثَ كَذَبَ وَإِذَا وَعَدَ أَخْلَفَ وَإِذَا عَاهَدَ غَدَرَ وَإِذَا خَاصَمَ فَجَرَ
