"There are four characteristics, whoever has them all is a pure hypocrite, and whoever has one of its characteristics, he has one of the characteristics of hypocrisy, until he gives it up: When he speaks he lies, when he makes a covenant he betrays it, when he makes a promise he breaks it, and when he disputes he resorts to obscene speech." In the narration of Sufyan (one of the narrators) it is: "And if he has one of them, he has one of the characteristics of hypocrisy."  

قَالَ رَسُولُ اللَّهِ ﷺ أَرْبَعٌ مَنْ كُنَّ فِيهِ كَانَ مُنَافِقًا خَالِصًا وَمَنْ كَانَتْ فِيهِ خَلَّةٌ مِنْهُنَّ كَانَتْ فِيهِ خَلَّةٌ مِنْ نِفَاقٍ حَتَّى يَدَعَهَا إِذَا حَدَّثَ كَذَبَ وَإِذَا عَاهَدَ غَدَرَ وَإِذَا وَعَدَ أَخْلَفَ وَإِذَا خَاصَمَ فَجَرَ غَيْرَ أَنَّ فِي حَدِيثِ سُفْيَانَ وَإِنْ كَانَتْ فِيهِ خَصْلَةٌ مِنْهُنَّ كَانَتْ فِيهِ خَصْلَةٌ مِنَ النِّفَاقِ
