2ـ الْحُسَيْنُ بْنُ مُحَمَّدٍ عَنْ مُعَلَّى بْنِ مُحَمَّدٍ عَنْ مُحَمَّدِ بْنِ جُمْهُورٍ الْعَمِّيِّ يَرْفَعُهُ قَالَ قَالَ رَسُولُ الله (صَلَّى اللهُ عَلَيْهِ وَآلِه) إِذَا ظَهَرَتِ الْبِدَعُ فِي أُمَّتِي فَلْيُظْهِرِ الْعَالِمُ عِلْمَهُ فَمَنْ لَمْ يَفْعَلْ فَعَلَيْهِ لَعْنَةُ الله.
2. Al-Husayn ibn Muhammad has narrated from Mu‘alla ibn Muhammad from Muhammad ibn Jumhur al-‘Ammi in a marfu‘ manner (rafa ’ahu), from the Messenger of Allah who has said the following. “When innovations emerge it will be obligatory for the scholars to make their knowledge public, otherwise, Allah will condemn them.”
