The second point is his description of Ka`b AlAhbar in imitation of some of late critics as being a Jew who feigned Islam to (freely) conspire against it and to corrupt its followers.
A : This disagrees with the wellknown information reported by Muslim scholars and transmitters of reports. For the scholars of Hadith reported from him, while Mu`awiyah (may Allah be pleased with him) and many righteous Salaf praised him.
Moreover, Muslim related from him in his "Sahih", while AlBukhari mentioned him in his book, "AlJami` AlSahih" without raising any suspicion about him. Also, AlHafizh Ibn Hajar referred to him in "AlIsabah and in AlTahdhib", and Ibn AlAthir referred to him in "Usd AlGhabah" without hurling any accusations at him.
In addition, AlHafizh Ibn Hajar stated in "Taqrib AlTahdhib" "Ka`b ibn Mati` AlHimyari, Abu Ishaq known as Ka`b AlAhbar , was a Thiqah (trustworthy) narrator from the people of Yemen who dwelled in AlSham (The Levant). He lived through paganism and Islam, and died during the caliphate of `Uthman (may Allah be pleased with him)". So, how can anyone who fears Allah and keeps his duty to Him accuse a person, who declared Islam, called to it and took part in what the Companions did, of being a Jew, with no warrant or argument supporting such a claim?
It is authentically reported that the Prophet (peace be upon him) warned the Muslims against vilifying each other, and informed us that the one who falsely accuses his fellow brother of something, the reviler would then be worthier of the hurled offensive trait than the one reviled.
Moreover, the fact that he reported some strange Israelite narrations (from the Jews) does not justify accusing him of being a Jew or of plotting against Islam, since the Prophet (peace be upon him) said, Report from the Children of Israel
