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.”
