What is the ruling and standing of the two narrators, Sulaym ibn Qays al-Hilali al-Kufi and Aban ibn Ayyash, according to the people of narration and understanding, and what is the ruling on the narrations transmitted from them?

Salim ibn Qays al-Hilali is not mentioned in the well-known biographical dictionaries. Rather, Ibn al-Nadim provided a biography for him in "Al-Fihrist," stating that he was among the companions of Amir al-Mu'minin Ali ibn Abi Talib. He fled from al-Hajjaj and sought refuge with Aban ibn Abi Ayyash, who sheltered him. Upon his death, Salim gave a book to Aban, known as "Kitab Salim ibn Qays al-Hilali," which was narrated solely by Aban from him.

As for Aban ibn Abi Ayyash, he was deemed weak by a number of scholars. Shu'ba said about him: "For me to commit fornication is more beloved to me than to narrate from Aban ibn Abi Ayyash." Ahmad ibn Hanbal said: "Nothing should be written from him." Yahya ibn Ma'in, Al-Nasa'i, and Al-Daraqutni described him as "abandoned." Ibn Adi noted that he did not intentionally lie, but he made mistakes and mixed up his narrations.
