It is narrated from Hazrat Jabir (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: When Kisra is destroyed, there will be no Kisra after him, and when Caesar is destroyed, there will be no Caesar after him. By Him in Whose hand is my soul, you will surely spend the treasures of both of them in the way of Allah, and that time will certainly come.
