Musannaf Ibn Abi Shaybah 39617 — The Hudaybiyah campaign

It is narrated from Sayyiduna Sahl bin Hunayf (may Allah be pleased with him): We were with the Messenger of Allah (peace and blessings be upon him), and had we been of the view to fight, we would have fought. This was during the peace concluded between the Messenger of Allah (peace and blessings be upon him) and the polytheists. Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) came, presented himself before the Messenger of Allah (peace and blessings be upon him) and said: "O Messenger of Allah (peace and blessings be upon him), are we not in the right and are they not in falsehood?" He (peace and blessings be upon him) said: "Indeed!" Then Sayyiduna Umar (may Allah be pleased with him) asked: "Will our slain not go to Paradise and their slain to Hell?" He (peace and blessings be upon him) said: "Indeed!" Sayyiduna Umar (may Allah be pleased with him) said: "Then why are we returning after agreeing to such a lowly thing? Allah Almighty has not yet judged between us and them." He (peace and blessings be upon him) said: "O son of al-Khattab, I am the Messenger of Allah. Allah Almighty will never let me be lost." The narrator says: Then Sayyiduna Umar (may Allah be pleased with him) could not bear it, and he went off in anger and came to Sayyiduna Abu Bakr (may Allah be pleased with him) and said: "O Abu Bakr, are we not in the right and are they not in falsehood?" Sayyiduna Abu Bakr (may Allah be pleased with him) said: "Indeed!" Sayyiduna Umar (may Allah be pleased with him) asked: "Will our slain not go to Paradise and their slain to Hell?" Sayyiduna Abu Bakr (may Allah be pleased with him) said: "Indeed." Sayyiduna Umar (may Allah be pleased with him) said: "Then why are we leaving after agreeing to such a lowly thing concerning our religion, when Allah Almighty has not yet judged between us and them?" Sayyiduna Abu Bakr (may Allah be pleased with him) said: "O son of al-Khattab, he is the Messenger of Allah, and Allah Almighty will never let him be lost." The narrator says: Then the Qur'an was revealed to the Prophet (peace and blessings be upon him) with (the promise of) victory, and he (peace and blessings be upon him) sent a man to Sayyiduna Umar (may Allah be pleased with him) and (having called him) had him read that Qur'an. Sayyiduna Umar (may Allah be pleased with him) said: "O Messenger of Allah (peace and blessings be upon him), is this a victory?" He (peace and blessings be upon him) said: "Yes!" At this Sayyiduna Umar's (may Allah be pleased with him) heart was gladdened and he went back.
