Sunan an-Nasa'i 5023

أَخْبَرَنَا عَمْرُو بْنُ يَحْيَى بْنِ الْحَارِثِ قَالَ حَدَّثَنَا الْمُعَافَى قَالَ حَدَّثَنَا زُهَيْرٌ قَالَ حَدَّثَنَا مَنْصُورُ بْنُ الْمُعْتَمِرِ عَنْ أَبِي وَائِلٍ قَالَ قَالَ عَبْدُ اللَّهِ ثَلَاثٌ مَنْ كُنَّ فِيهِ فَهُوَ مُنَافِقٌ إِذَا حَدَّثَ كَذَبَ وَإِذَا اؤْتُمِنَ خَانَ وَإِذَا وَعَدَ أَخْلَفَ فَمَنْ كَانَتْ فِيهِ وَاحِدَةٌ مِنْهُنَّ لَمْ تَزَلْ فِيهِ خَصْلَةٌ مِنْ النِّفَاقِ حَتَّى يَتْرُكَهَا

It was narrated that Abu Wa'il said:"Abdullah said: 'There are three (traits), whoever has them is a hypocrite: When he speaks, he lies; when he is entrusted with something, he betrays that trust; and when he makes a promise, he breaks it. Whoever has one of these (traits) then a trait of hypocrisy has not ceased in him, until he leaves it.'" (Sahih Mawquf)
