Chapter: To give a Baia for not to flee during a battle

When we reached (Hudaibiya) in the next year (of the treaty of Hudaibiya), not even two men amongst us agreed unanimously as to which was the tree under which we had given the pledge of allegiance, and that was out of Allah's Mercy. (The sub narrator asked Naf'i, "For what did the Prophet (ﷺ) take their pledge of allegiance, was it for death?" Naf'i replied "No, but he took their pledge of allegiance for patience.")

that in the time (of the battle) of Al-Harra a person came to him and said, "Ibn Hanzala is taking the pledge of allegiance from the people for death." He said, "I will never give a pledge of allegiance for such a thing to anyone after Allah's Messenger (ﷺ)."

Salama said, "I gave the Pledge of allegiance (Al-Ridwan) to Allah's Messenger (ﷺ) and then I moved to the shade of a tree. When the number of people around the Prophet (ﷺ) diminished, he said, 'O Ibn Al-Akwa` ! Will you not give to me the pledge of Allegiance?' I replied, 'O Allah's Messenger (ﷺ)! I have already given to you the pledge of Allegiance.' He said, 'Do it again.' So I gave the pledge of allegiance for the second time." I asked 'O Abu Muslim! For what did you give he pledge of Allegiance on that day?" He replied, "We gave the pledge of Allegiance for death."

On the day (of the battle) of the Trench, the Ansar were saying, "We are those who have sworn allegiance to Muhammad for Jihaid (for ever) as long as we live." The Prophet (ﷺ) replied to them, "O Allah! There is no life except the life of the Hereafter. So honor the Ansar and emigrants with Your Generosity."

My brother and I came to the Prophet (ﷺ) and I requested him to take the pledge of allegiance from us for migration. He said, "Migration has passed away with its people." I asked, "For what will you take the pledge of allegiance from us then?" He said, "I will take (the pledge) for Islam and Jihad."
