Umar bin Rabi'ah narrates: Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) sent for Ka'b al-Ahbar and asked: "O Ka'b! How have you found my description?" He said: "I have found your description to be that you are a horn of iron." Sayyiduna Umar (may Allah be pleased with him) asked: "What is meant by a horn of iron?" Ka'b said: "A ruler who will be firm; the blame of any blamer will not take hold of him in the matter of Allah Almighty." Sayyiduna Umar (may Allah be pleased with him) asked: "And what else?" He said: "And that after you there will be a caliph whom a wrongdoing group will kill." Sayyiduna Umar (may Allah be pleased with him) asked: "Then what will happen?" Ka'b said: "After that there will be trials."
Tabarani recorded it, and its narrators are thiqat (trustworthy).
