It is narrated from Hazrat Shaddad (may Allah be pleased with him) that once the Holy Prophet (peace and blessings be upon him) came out for either the Zuhr or Asr prayer, carrying either Imam Hasan (may Allah be pleased with him) or Imam Husain (may Allah be pleased with him). He advanced and seated him to one side, then pronounced the takbeer and began the prayer. When he went into prostration, he prolonged it greatly. I raised my head in between and saw that a child was riding on the back of the Holy Prophet (peace and blessings be upon him) while he was still in prostration. Seeing this, I returned to prostration. When the Holy Prophet (peace and blessings be upon him) finished the prayer, the people said: "O Messenger of Allah! Today you made the prostration in this prayer very long. We thought perhaps some incident had occurred or revelation was being sent down upon you?" The Holy Prophet (peace and blessings be upon him) replied: "None of these things happened. Rather, my son was riding on my back, and I did not wish to hurry him until he had fulfilled his desire."
