493年,喀瓦德为了亲政而强迫苏赫拉退休,让他回到家乡设拉子当省长,以为远离首都的苏赫拉不可能再有干涉王权的机会。但结果出乎喀瓦德意料,曾经的“救国英雄”苏赫拉居然保持着强大威望,依然遥控著朝政,并多次吹嘘自己拥立喀瓦德的功绩和恩情。于是手段过人的喀瓦德,以拉一打一的方式,成功拉拢与苏赫拉敌对的大贵族雷之沙普尔(英语:Shapur of Ray),让雷之沙普尔率领自己的兵马攻入设拉子,并把苏赫拉送到首都泰西封囚禁著。喀瓦德一世鉴于中央军过半数仍爱戴或同情苏赫拉,于是在同年(493年)害死了苏赫拉。这样的雷霆手段和忘恩负义行动,引起一部分显贵和杰出官僚的不满,削弱了喀瓦德的支持力道和国王应有的道德合法性。
