Are narratives that contain fabricators and liars suitable as evidence or sources, and what are the authentic narratives reported concerning the Tuba tree, and does it produce Houris, Ghilman (eternal youths), and animals?

The weakness considered in corroborating and supporting narrations is that in which the weakness of the narrator has not reached the point of abandonment. In the context of corroborating and supporting narrations, it is overlooked to narrate from a weak narrator whose weakness is slight. As for a hadith whose weakness is severe, it is neither relied upon nor used for corroboration, such as the hadith of liars and abandoned narrators.

The hadith: "Glad tidings to them and an excellent return! A tree planted by Allah with His Hand, into which He breathed of His Spirit, it grows with adornments and garments, and its branches can be seen from beyond the wall of Paradise" is fabricated. Its defect is Al-Hasan ibn Shabib, and Muhammad ibn Ziyad Al-Jurayri is unknown.

The narrations reported concerning the tree of Tuba are not free from weakness or scrutiny in their chains of transmission. Among them is the hadith: "Yes, and in it is a tree called Tuba...it resembles a tree in Syria called the Walnut, it grows on a single trunk, and its upper part spreads out," and this hadith is amenable to improvement.
