It is narrated from Sa’d bin Ibrahim, he heard from a man of Banu Makhzum, who relates from his uncle that Sayyiduna Muawiyah (may Allah be pleased with him) wanted to take the land called Wahat belonging to Sayyiduna Abdullah bin Amr (may Allah be pleased with him), but he ordered his slaves, so they picked up their tools and got ready to fight. I went to them and asked: What is this? They said: I heard the Messenger of Allah (peace and blessings be upon him) say: If a Muslim is wronged and he fights back and is killed, then he will be a martyr.
