All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.
The first Hadeeth was indeed narrated by Abu Ya‘la from Jaabir . Ibn Katheer related it in his Tafseer and said thereafter: "This Hadeeth is very strange and is contextually odd. The only person to report it was Al-Qaasim Ibn ‘Abd-ur-Rahmaan, about whom Yahya Ibn Ma‘een said: “He is insufficient.” Abu Haatim Ar-Raazi considered him weak and Ibn ‘Adiyy said: “He is unknown".
As for the report of Ka‘b, it was mentioned by Ibn Katheer in his Tafseer without any commentary and we could not find any comments elsewhere either. However, it is known that Ka‘b Al-Ahbaar would often relate Israa’eeliyyaat [stories from Bani Israa’eel] as he was a Jew who became Muslim. The researching scholars concluded that there are three types of Israa’eeliyyaat:
1. That which is definitely true, as it coincides with what is established by the Islamic Sharee'ah.
2. That which is definitely false, as it contradicts the source texts of the Islamic Sharee'ah.
3. That which is neither declared true nor false. Ibn Katheer mentioned these types in the introduction to his Tafseer, saying about the third type: It is allowed to narrate this type of report due to the saying of the Prophet, sallallaahu ‘alayhi wa sallam: “Narrate from Bani Israa’eel. There is no blame in doing so.” [Al-Bukhari] This is what is neither declared true nor false, due to his saying: “Do not declare them to be truthful and do not declare them to be liars.” [Al-Bukhari]. For more information on this, see Fatwa 91119.
On the other hand, we looked up the rest of the reports you mentioned and found they are equal to the above, as none of them can be used as evidence. Their basis is only found in the Israa’eeliyyaat and you know what is said about that.
As long as these reports remain inauthentic, time should not be wasted by trying to understand them and by deriving meanings from them. The Muslim should not occupy himself with the likes of these narrations and should instead engage in something beneficial.
Allaah Knows best.
