4 حَدَّثَنِي مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ جَعْفَرٍ عَنْ أَبِيهِ عَنْ هَارُونَ بْنِ مُسْلِمٍ عَنْ عَلِيِّ بْنِ حَسَّانَ الْوَاسِطِيِّ عَنْ بَعْضِ أَصْحَابِنَا عَنِ الرِّضَا (ع) فِي إِتْيَانِ قَبْرِ أَبِي الْحَسَنِ (ع) قَالَ صَلُّوا فِي الْمَسَاجِدِ حَوْلَهُ
4. Muḥammad ibn ‘Abdillāh ibn Ja’far narrated to me from his father, from Hārūn ibn Muslim, from ‘Ali ibn Ḥassān Al-Wāsiťi, from some of our companions, who said: I asked Imam Riďā about going to (the Ziyārah of) the grave of Abil Ḥasan (Imam Kāżim ). Imam replied, “Establish prayers in the mosques around the grave.”
