4 وَ عَنْهُ عَنْ أَحْمَدَ بْنِ إِدْرِيسَ عَنِ الْعَمْرَكِيِّ عَنْ صَنْدَلٍ عَنْ دَاوُدَ بْنِ فَرْقَدٍ قَالَ قُلْتُ لِأَبِي عَبْدِ اللَّهِ (ع) مَا لِمَنْ زَارَ الْحُسَيْنَ (ع) فِي كُلِّ شَهْرٍ مِنَ الثَّوَابِ قَالَ لَهُ [مِنَ الثَّوَابِ] ثَوَابُ مِائَةِ أَلْفِ شَهِيدٍ مِثْلَ شُهَدَاءِ بَدْرٍ

4. My father narrated to me from Aḥmad ibn Idrīs, from ‘Amraki, from Sandal, from Dāwūd ibn Farqad, who said: I asked Abā ‘Abdillāh (Imam Sādiq ), “What is the reward for those who go to the Ziyārah of Ḥusain every month?” Imam replied, “They will earn the reward of one hundred thousand martyrs like the martyrs of (the Battle of) Badr.”
