Musannaf Ibn Abi Shaybah 3498 — Those who said: the people are led

Sayyiduna Ibn Umar (may Allah be pleased with them both) says: When the Muhajirun came from Makkah, they encamped near Quba. On that occasion Sayyiduna Salim, the freed slave of Abu Hudhayfah (may Allah be pleased with him), used to lead them in prayer, because he knew the most Qur'an among them. Among those people were Sayyiduna Abu Salamah bin Abd al-Asad and Sayyiduna Umar bin al-Khattab (may Allah be pleased with them both).
