Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: On the day of the Battle of the Trench, the Prophet (peace and blessings be upon him) became hidden (from people's sight), except that six people were different: four of them were from the Muhajirun, namely Sayyiduna Talhah (may Allah be pleased with him), Sayyiduna al-Zubayr (may Allah be pleased with him), Sayyiduna Ali (may Allah be pleased with him) and Sayyiduna Sa'd (may Allah be pleased with him); and those from the Ansar were Sayyiduna Abu Dujanah (may Allah be pleased with him) and Sayyiduna al-Harith bin al-Simmah (may Allah be pleased with him).
Al-Tabarani recorded it; its chain contains a group of narrators whom I do not know.
