Musnad Ahmad

Sayyiduna Abu Wa'il says that Sabi bin Ma'bad was from the rural tribe of Banu Taghlib and was a Christian who accepted Islam. He asked the people, "Which is the most virtuous deed?" The people replied, "Jihad in the way of Allah." So he intended to participate in Jihad. Meanwhile, someone asked him, "Have you performed Hajj?" He said, "No!" The person said, "First perform Hajj and Umrah, then participate in Jihad." So he set out with the intention of Hajj, and upon reaching the Miqat, he entered into Ihram for both Hajj and Umrah. When Zaid bin Suhan and Salman bin Rabiah found out, they said, "This person is more misguided than his camel." When Sabi presented himself before Sayyiduna Umar (may Allah be pleased with him), he mentioned to him what Zaid and Salman had said. Sayyiduna Umar al-Faruq (may Allah be pleased with him) said, "You have been guided to the Sunnah of your Prophet (peace and blessings be upon him)." The narrator of the hadith says, "I asked Abu Wa'il, 'Did Sabi himself narrate this to you?' He replied in the affirmative."
