Musnad Abi Ya'la 1715 — he related: The first of the Companions

It is narrated from Sayyiduna al-Bara' bin Azib (may Allah be pleased with him) that he related: "The first of the Companions of the Messenger of Allah (peace and blessings be upon him) to arrive (in Madinah, emigrating) were Sayyiduna Mus'ab bin Umayr (may Allah be pleased with him) and Sayyiduna Ibn Umm Maktum (may Allah be pleased with him); these two used to teach people the Noble Qur'an." Then he related: "After that Sayyiduna Bilal (may Allah be pleased with him), Sayyiduna Sa'id (may Allah be pleased with him) and Sayyiduna Ammar bin Yasir (may Allah be pleased with him) arrived." Then he related: "Then Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) arrived with twenty other Companions of the Messenger of Allah (peace and blessings be upon him), and after that the Messenger of Allah (peace and blessings be upon him) himself arrived. I never saw the people of Madinah as happy about anything as they were at the arrival of the Messenger of Allah (peace and blessings be upon him)", so much so that even the slave-girls began calling out: "The Messenger of Allah (peace and blessings be upon him) has arrived!" He related: "By the time he (peace and blessings be upon him) arrived, I had already read (that is, memorised) Surah 'Sabbih isma rabbika al-a'la' (Glorify the name of your Lord, the Most High) and several other surahs of the Mufassal."
