How Far the Muslims were Ready to Fight and Sacrifice

Two incidents occurred during the last hours of the fight. Which revealed for certain how far the Muslims were ready to fight and sacrifice in the way of Allâh:
Ka‘b bin Malik said: I was one of those Muslims who fought in Uhud and witnessed the polytheists’ act of barbarity in mutilating the dead bodies, but I passed them because I couldn’t stand it. Then I saw an armed stout idolater pass through the Muslims and say: "Gather them up and combine them in the way that sheep are gathered and slaughtered." Similarly I saw an armed Muslim waiting for him. I walked towards them till I stood behind him. Comparing both of them, I found that the disbeliever was better than the other in arms and figure. I kept on watching them till they were engaged in single combat. The Muslim thrust at the disbeliever with his sword that went down his hip and split it into two. When the Muslim unveiled his face, he said: "What about that, Ka‘b. I am Abu Dujana." [Al-Bidaya wan Nihaya 4/17]
Some Muslim women came to the battlefield when the fight was over. Anas said: I saw ‘Aishah bint Abu Bakr [R] with Umm Sulaim. Their garments were gathered up so I could see their anklets. They carried water bags on their shoulders and emptied them into the mouths of people. [Sahih Al-Bukhari 1/403, 2/581] Then they would go back to fill them and come back to do the same. ‘Umar said: "Umm Saleet used to carry water bags to us on Uhud Day." [ibid 1/401]

When Umm Aiman, who was one of those Muslim women who saw the defeated Muslim fighters entering Madinah, she started throwing dust at their faces rebukingly saying: "Here is a spinning wheel, take it! and give up carrying swords." Then she raced to the battlefield. There she watered the wounded. Hibban bin Al-‘Arqa shot an arrow at her, she fell down and her clothes were lifted up. Seeing that, the enemy of Allâh, burst into laughter. That sight upset the Messenger of Allâh [pbuh], so he gave Sa‘d bin Abi Waqqas an arrow lacking an arrow-head and said "Shoot it". Sa‘d shot it, it pierced the idolater’s throat. He fell down and some parts of his body were revealed. The Messenger of Allâh [pbuh] then laughed so much that his molars could be seen. Sa‘d avenged her and Allâh responded to her supplication. [As-Seerat Al-Halabiyah 2/22]
