Ali b. Ibrahim has reported from Imam Baqir (a.s.) regarding the verse: “And whoever defends himself after his being oppressed.” (Surah Shura (42):41)
“It means that the Qaim and his companions because it is them, against whom there is no way and when the Qaim arises he would take revenge from the Bani Umayyah, the deniers and those hostile to him and his companions.”
