Musannaf Ibn Abi Shaybah 34364 — Reports on al-Hasan and al-Husayn

Abdullah bin Shaddad (may Allah have mercy on him) said that his father, Sayyiduna Shaddad (may Allah be pleased with him), said: The Messenger of Allah (peace and blessings be upon him) was called to prayer, and he (peace and blessings be upon him) came out carrying Sayyiduna al-Hasan (may Allah be pleased with him) or Sayyiduna al-Husayn (may Allah be pleased with him). He (peace and blessings be upon him) seated him by his side. Then in the course of his prayer he (peace and blessings be upon him) performed a prostration and made it very long. My father said: I raised my head from among all the people and saw a child sitting on the back of the Messenger of Allah (peace and blessings be upon him), so I returned my head to prostration. When the Messenger of Allah (peace and blessings be upon him) ended the prayer with the salam, the people asked: "O Messenger of Allah (peace and blessings be upon him), today in your prayer you (peace and blessings be upon him) performed a prostration such as you (peace and blessings be upon him) had never performed in your whole life. Was some revelation being sent to you (peace and blessings be upon him)?" He (peace and blessings be upon him) said: "No, but my son had climbed on me as a rider, and I disliked hurrying up until he had satisfied his wish."
