باب بَيَانِ خِصَالِ الْمُنَافِقِ ‏‏

'Uqba b. Mukarram al-'Ami reported that he heard 'Ala' b. 'Abdur-Rahman narrating this hadith with this chain of transmitters and he said:

Three are the signs of a hypocrite, even if he observed fast and prayed and asserted that he was a Muslim.
حَدَّثَنَا عُقْبَةُ بْنُ مُكْرَمٍ الْعَمِّيُّ، حَدَّثَنَا يَحْيَى بْنُ مُحَمَّدِ بْنِ قَيْسٍ أَبُو زُكَيْرٍ، قَالَ سَمِعْتُ الْعَلاَءَ بْنَ عَبْدِ الرَّحْمَنِ، يُحَدِّثُ بِهَذَا الإِسْنَادِ وَقَالَ ‏ "‏ آيَةُ الْمُنَافِقِ ثَلاَثٌ وَإِنْ صَامَ وَصَلَّى وَزَعَمَ أَنَّهُ مُسْلِمٌ ‏"‏ ‏.‏
