The Prophet ﷺ said, "Whoever has the following four (characteristics) will be a pure hypocrite and whoever has one of the following four characteristics will have one characteristic of hypocrisy unless and until he gives it up. 1. Whenever he is entrusted, he betrays. 2. Whenever he speaks, he tells a lie. 3. Whenever he makes a covenant, he proves treacherous. 4. Whenever he quarrels, he behaves in a very imprudent, evil and insulting manner."  

أَنَّ النَّبِيَّ ﷺ قَالَ أَرْبَعٌ مَنْ كُنَّ فِيهِ كَانَ مُنَافِقًا خَالِصًا وَمَنْ كَانَتْ فِيهِ خَصْلَةٌ مِنْهُنَّ كَانَتْ فِيهِ خَصْلَةٌ مِنَ النِّفَاقِ حَتَّى يَدَعَهَا إِذَا اؤْتُمِنَ خَانَ وَإِذَا حَدَّثَ كَذَبَ وَإِذَا عَاهَدَ غَدَرَ وَإِذَا خَاصَمَ فَجَرَ  

The Prophet ﷺ said, "The signs of a hypocrite are three: 1. Whenever he speaks, he tells a lie. 2. Whenever he promises, he always breaks it (his promise ). 3. If you trust him, he proves to be dishonest. (If you keep something as a trust with him, he will not return it.)"  

عَنِ النَّبِيِّ ﷺ قَالَ آيَةُ الْمُنَافِقِ ثَلاَثٌ إِذَا حَدَّثَ كَذَبَ وَإِذَا وَعَدَ أَخْلَفَ وَإِذَا اؤْتُمِنَ خَانَ
