Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) narrates: Sayyiduna Imam Husayn (may Allah be pleased with him) came running while the Prophet (peace and blessings be upon him) was praying. He clung to the neck of the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) stood up, took hold of his hand, and kept holding him until he went into bowing (ruku').
Al-Tabarani recorded it, and there is a difference of opinion about using its narrators as evidence.
