It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "When Chosroes perishes, there will be no other Chosroes after him, and when Caesar perishes, there will be no other Caesar after him; and by the One in whose Hand is my soul, their treasures will surely be spent in the way of Allah."
No one narrated this hadith from Aban bin Taghlib (may Allah have mercy on him) except Ibn al-Ajlah (may Allah have mercy on him), and Minjab (may Allah have mercy on him) is alone in narrating it.
