Strive for peace & harmony in relationships; Respect each other; Follow Islamic teachings while making agreements/contracts

This hadith is about the Prophet Muhammad's peace agreement with the people of Hudaibiya. It was narrated by Abu Ishaq who heard Bars' b. Azib say that when they made peace, 'Ali wrote an agreement between them and mentioned Muhammad as the Messenger of Allah in it. This hadith teaches us that we should always strive for peace and harmony in our relationships with others, even if we have to make compromises to do so. We should also be respectful towards each other and recognize each other's rights and responsibilities in order to maintain peaceful relations between us all. Furthermore, this hadith also shows us how important it is to follow Islamic teachings when making agreements or contracts so that everyone involved can benefit from them equally without any injustice or unfairness occurring on either side.
