مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ أَبِي نَصْرٍ عَنْ دَاوُدَ بْنِ سِرْحَانَ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ قَالَ رَسُولُ اللَّهِ ( صلى الله عليه وآله ) إِذَا رَأَيْتُمْ أَهْلَ الرَّيْبِ وَ الْبِدَعِ مِنْ بَعْدِي فَأَظْهِرُوا الْبَرَاءَةَ مِنْهُمْ وَ أَكْثِرُوا مِنْ سَبِّهِمْ وَ الْقَوْلَ فِيهِمْ وَ الْوَقِيعَةَ وَ بَاهِتُوهُمْ كَيْلَا يَطْمَعُوا فِي الْفَسَادِ فِي الْإِسْلَامِ وَ يَحْذَرَهُمُ النَّاسُ وَ لَا يَتَعَلَّمُوا مِنْ بِدَعِهِمْ يَكْتُبِ اللَّهُ لَكُمْ بِذَلِكَ الْحَسَنَاتِ وَ يَرْفَعْ لَكُمْ بِهِ الدَّرَجَاتِ فِي الْآخِرَةِ
Muhammad Bin Yahya, from Muhammad Bin Al Husayn, from Ahmad Bin Muhammad Bin Abu Nasr, from Dawood Bin Sirham,
(It has been narrated) from Abu Abdullah-asws having said: ‘Rasool-Allah-saww said: ‘Whenever you see the people of the doubts and the innovation from after me-saww, so display the disownment from them, and frequent from ‘سَبِّهِمْ’ insulting them, and speaking regarding them, and the encountering them, and the defaming them, perhaps they would not covet (plant) the mischief in Al-Islam, and caution the people not to learn from their innovations, Allah-azwj would Write the good deeds for you due to that, and Raise the levels for you in the Hereafter due to that.[1]
