Sayyiduna Jabir (may Allah be pleased with him) said: On the day of al-Hudaybiyah we were 1,400. We pledged allegiance to him (peace and blessings be upon him) while Sayyiduna Umar (may Allah be pleased with him) was holding his (peace and blessings be upon him) hand under the tree. We did not pledge allegiance to him (peace and blessings be upon him) to die, but rather that we would not flee.
