حَدَّثَنَا عُقْبَةُ بْنُ مُكْرَمٍ الْعَمِّيُّ، حَدَّثَنَا يَحْيَى بْنُ مُحَمَّدِ بْنِ قَيْسٍ أَبُو زُكَيْرٍ، قَالَ: سَمِعْتُ الْعَلَاءَ بْنَ عَبْدِ الرَّحْمَنِ
يُحَدِّثُ بِهَذَا الإِسْنَادِ وَقَالَ: «آيَةُ الْمُنَافِقِ ثَلَاثٌ وَإِنْ صَامَ وَصَلَّى وَزَعَمَ أَنَّهُ مُسْلِمٌ»
He heard Ala ibn 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.
