1. My father and Muḥammad ibn Ḥasan both narrated to me from Ḥasan ibn Mattīl, from Sahl ibn Ziyād Al-Ādami, from Muḥammad ibn ‘Abdillāh, from Sāliḥ ibn ‘Uqbah, from Abī Shibl, who said: I asked Abā ‘Abdillāh (Imam Sādiq عليه السلام), “Should I go to the Ziyārah of the grave of Ḥusain عليه السلام?” Imam عليه السلام replied, “Go to the Ziyārah of the Blessed One and establish prayers in full form next to his grave.” I asked, “Establish prayers in full form next to him?!” Imam عليه السلام replied, “(Establish prayers) in full form.” I said, “(But) some of our companions narrate that prayers should be established in Taqsīr?!” Imam عليه السلام replied, “Those who are weak do this.” The above Ḥadīth has also been narrated to me through the following chain: Muḥammad ibn Ya’qūb, from all of his scholars, from Sahl ibn Ziyāh, from Muḥammad ibn ‘Abdillāh, from Sāliḥ ibn ‘Uqbah, from Abī Shibl, from Abī ‘Abdillāh عليه السلام.
