Sayyidina Abu Huraira (RA) reported that Allah’s Messenger (SAW) said, “When the Chosroes is killed, there will be no Chosroes after him. When the Caesar is killed, there will be no Caesar after him. By Him in Whose hand is my soul, you will give away their treasures in the cause of Allah (in jihad).”
[Bukhari 3027]
