3. Muḥammad ibn Ja’far Al-Razzāz narrated to me from Muḥammad ibn Ḥusain ibn Abil Khaťťāb, from Abī Dāwūd Al-Mustariq, from Um Sa’īd Al-Aḥmasiyyah, who said: Abū ‘Abdillāh (Imam Sādiq ) asked me, “O Um Sa’īd! Do you go to the Ziyārah of the grave of Ḥusain ?” I replied, “Yes.” Imam said, “Go to his Ziyārah, for verily going to the Ziyārah of the grave of Ḥusain is WĀJIB (mandatory) on both men and women.”
