It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever is killed fighting against an injustice (in defence of his right) is a martyr."
Imam al-Tabarani (may Allah have mercy on him) said: "Only Amr bin Shimr narrated this hadith from al-A'mash, and Ubayd al-Nahhas is alone in narrating it."
