Musnad Ahmad

It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that once we were offering the Isha prayer with the Noble Prophet (peace and blessings be upon him). When the Noble Prophet (peace and blessings be upon him) went into prostration, Hazrat Hasan and Husain (may Allah be pleased with them) jumped and climbed onto the blessed back of the Noble Prophet (peace and blessings be upon him). When the Noble Prophet (peace and blessings be upon him) raised his head from prostration, he gently caught them by extending his hand behind and set them down on the ground. Throughout the prayer, whenever the Noble Prophet (peace and blessings be upon him) went into prostration, both of them would do the same, until the Noble Prophet (peace and blessings be upon him) finished the prayer and seated them on his thigh. I stood up and said to the Noble Prophet (peace and blessings be upon him), "O Messenger of Allah (peace and blessings be upon him), should I take both of them back?" At that moment, a light appeared, and the Noble Prophet (peace and blessings be upon him) said to both of them, "Go to your mother," and that light remained until they entered their house.
