٤ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ أَبِي نَصْرٍ عَنْ دَاوُدَ بْنِ سِرْحَانَ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ قَالَ رَسُولُ الله (صَلَّى اللهُ عَلَيْهِ وآلِه) إِذَا رَأَيْتُمْ أَهْلَ الرَّيْبِ وَالْبِدَعِ مِنْ بَعْدِي فَأَظْهِرُوا الْبَرَاءَةَ مِنْهُمْ وَأَكْثِرُوا مِنْ سَبِّهِمْ وَالْقَوْلَ فِيهِمْ وَالْوَقِيعَةَ وَبَاهِتُوهُمْ كَيْلا يَطْمَعُوا فِي الْفَسَادِ فِي الإسْلامِ وَيَحْذَرَهُمُ النَّاسُ وَلا يَتَعَلَّمُوا مِنْ بِدَعِهِمْ يَكْتُبِ الله لَكُمْ بِذَلِكَ الْحَسَنَاتِ وَيَرْفَعْ لَكُمْ بِهِ الدَّرَجَاتِ فِي الآخِرَةِ.
4. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Ahmad ibn Muhammad ibn abu Nasr from Dawud ibn Sarhan from Abu ‘Abdillah  who has said the following: “The Messenger of Allah has said, ‘When you after me find people of heresy and skepticism express your disapproval of them and increase your condemnation, words and opposition to and evidence against them so they may not become greedy to bring destruction to Islam. You must warn people against them and against learning their heretic ideas. Allah will reward you for this and will raise your position in the next life.’”
