Abd Allah ibn Umar 250 reported that One of the Yemenis came to Ka’b al-Ahbar and said to him: The Jewish Rabbi so and so sent me to hand you a letter. Ka’b said: Give it. The man said: He says to you: Weren’t you an honourable influential master! So what brought you out of your religion toward Ummah of Muhammad? Ka’b replied: Do you intend to return to him? He said: Yes.

Ka’b said: When you go back to him, catch him from his garment skirt so as not to let him flee, and say to him: He says to you: I beg you by That Who split the sea for Moses, and I ask you by Allah Who gave Musa ibn Imran the tablets which containing the knowledge of everything! don’t you find in Allah’s words that the Ummah of Muhammad are three thirds: one third of them will verily enter paradise without reckoning.

The second third will be subjected to slight reckoning, and enter paradise afterwards. And the other third will enter the heavens through the intercession of Ahmad, he will verily reply: Yea. Then say to him: Ka’b says to you: Make me within any of these thirds that you wish!” In al-Isabah, Ibn Hajar says that he related from the Prophet mursal traditions, and from him (Ka’b) some of the reported, like Ibn Umar, Abu Hurayrah, Ibn Abbas, Ibn al-Zubayr and Mu’awiyah beside others.

251 Al-Dhahabi, in Siyar A’lam al-nubala’, writes: From him hadith was reported by Abd Allah ibn Hanzalah, 252 Aslam mawla of Umar, Tubay’ al-Himyari and Abu Salam al-Aswad. Also from him a number of the Followers, like ‘Ata’ ibn Yasar and others, reported some mursal traditions (with no reference to chain of transmitters). Some of his narrations appeared in Sunan of Abu Dawud and of al-Tirmidhi and al-Nasa’i.

253 Professor Sa'id al-Afghani, in an article published in al-Risalah Journal, stated that the first Zionist being Abd Allah ibn Saba'. In reply to this I wrote an elaborated article proving in it that the first (staunchest) Zionist being Ka'b al-Ahbar. This reply appeared in issue No. 656 of al-Risalah. Al-Islam wa al-hadarah al-Arabiyyah, p. 164.

How can't Ka'b al-Ahbar be described as having abundant knowledge, while it was him who said to Qays ibn Kharshah al-Qausi: "No span of the earth but was recorded in the Torah, which Allah revealed to His prophet Musa (peace be upon him), with whatever will be on it and whatever goes out of it till the Day of Resurrection." This hadith was reported by al-Tabari and al-Bayhaqi in al-Dala'il, beside Ibn Abd al-Barr in al-Isti'ab, Vol. II, p. 533.
