Hadith #17

17ـ وَبِهَذَا الاسْنَادِ عَنِ الْوَشَّاءِ عَنْ عَلِيِّ بْنِ الْحَسَنِ عَنْ أَبَانِ بْنِ تَغْلِبَ قَالَ قَالَ أَبُو عَبْدِ الله (عَلَيْهِ السَّلام) كَيْفَ أَنْتَ إِذَا وَقَعَتِ الْبَطْشَةُ بَيْنَ الْمَسْجِدَيْنِ فَيَأْرِزُ الْعِلْمُ كَمَا تَأْرِزُ الْحَيَّةُ فِي جُحْرِهَا وَاخْتَلَفَتِ الشِّيعَةُ وَسَمَّى بَعْضُهُمْ بَعْضاً كَذَّابِينَ وَتَفَلَ بَعْضُهُمْ فِي وُجُوهِ بَعْضٍ قُلْتُ جُعِلْتُ فِدَاكَ مَا عِنْدَ ذَلِكَ مِنْ خَيْرٍ فَقَالَ لِي الْخَيْرُ كُلُّهُ عِنْدَ ذَلِكَ ثَلاثاً.

17. through the same chain of narrators it is narrated from al-Washsha’ from Ali ibn al-Hassan from Aban ibn Taghlib who has said the following. “How would it be with you when an lagre scale attack would take place between the two mosques. Thereafter, knowledge will become obscure as the snake goes in to its hiding place. The Shi‘a (Muslims) will hold differences and one group will call the group liars and one group will spit onto the faces of the aother.” I then said, “May Allah take my soul in service for your cause, there will be nothing good in such conditions.” The Imam (a.s.) said, “All goodness will be there.” He said it three times.
