Participate in important events like battles or treaties to earn rewards from Allah SWT .

This hadith is about how the Prophet Muhammad (PBUH) assured a slave of Hatib bin Abi Balt'ah that he would not enter the Fire, as he had participated in two important events; the battle of Badr and the treaty of Al-Hudaybiyah. The battle of Badr was fought between Muslims and nonbelievers, while Al-Hudaybiyah was a peace treaty between Muslims and nonbelievers. This hadith teaches us that those who participate in such important events will be rewarded with paradise by Allah SWT. It also teaches us to be patient when faced with difficult situations, as Allah SWT will always reward those who are patient with His mercy.
