Tolerance to Enemies:

When people of the village of Ta'if rejected him, stoned him, ejected him, and made his feet to bleed, the angel Gabriel came to him and said, "Allah has heard what your people say to you and how they reject you. He has ordered the angels of the mountains to obey whatever you tell them to do." The angel of the mountains called him, greeted him and said, "Send me to do what you wish. If you wish, I will crush them between the two mountains of Mecca." The Prophet said, "Rather, I hope that Allah will bring forth from their loins those who will worship Allah alone and not associate anything with Him.” ( Bukhari and Muslim)

In one of the Prophet's  battles called al-Ahzab or Al-Khandaq, Salman advised the Prophet to dig trenches around Madinah in defense of the city, a suggestion which the Prophet happily accepted. He accepted that so that there would be no blood-shedding among the enemies.
