493年,喀瓦德為了親政而強迫蘇赫拉退休,讓他回到家鄉設拉子當省長,以為遠離首都的蘇赫拉不可能再有干涉王權的機會。但結果出乎喀瓦德意料,曾經的「救國英雄」蘇赫拉居然保持著強大威望,依然遙控著朝政,並多次吹噓自己擁立喀瓦德的功績和恩情。於是手段過人的喀瓦德,以拉一打一的方式,成功拉攏與蘇赫拉敵對的大貴族雷之沙普爾(英语:Shapur of Ray),讓雷之沙普爾率領自己的兵馬攻入設拉子,並把蘇赫拉送到首都泰西封囚禁著。喀瓦德一世鑑於中央軍過半數仍愛戴或同情蘇赫拉,於是在同年(493年)害死了蘇赫拉。這樣的雷霆手段和忘恩負義行動,引起一部分顯貴和傑出官僚的不滿,削弱了喀瓦德的支持力道和國王應有的道德合法性。
