Majma al-Zawaid — Hadith 15076

Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates: We performed the Isha prayer with the Prophet (peace and blessings be upon him). When the Prophet (peace and blessings be upon him) went into prostration, Sayyiduna Hasan (may Allah be pleased with him) and Sayyiduna Husayn (may Allah be pleased with him) climbed onto his back. When the Prophet (peace and blessings be upon him) raised his head, he took hold of them both from behind; he held them gently and moved them off his back. When he went into prostration again, the two boys did the same thing again, until, when the Prophet (peace and blessings be upon him) completed the prayer, he sat them both in his lap. The narrator says: I got up and came to him, and I said: "O Messenger of Allah! Shall I take them both back?" The narrator says: Just then there was a flash of lightning (or something like a light), and the Prophet (peace and blessings be upon him) said to them both: "Go to your mother!" The narrator says: That light remained until they both reached their mother.
Ahmad recorded it, and al-Bazzar recorded it in abridged form. In it he recorded these words: "On a dark night." Ahmad's narrators are thiqat (trustworthy).
