Hadith 2:21
Abu Huraira reported God’s messenger as saying, “Two qualities are not found together in a hypocrite:
good behaviour and knowledge of religion.” Tirmidhi transmitted it.
وَعَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: " خَصْلَتَانِ لَا تَجْتَمِعَانِ فِي مُنَافِقٍ: حُسْنُ سَمْتٍ وَلَا فِقْهٌ فِي الدّين " رَوَاهُ التِّرْمِذِيّ
