What is the authenticity of what was narrated from Ja'far ibn Muhammad, from his father, from his grandfather, concerning the creation of the Throne from a jewel, and what is the authenticity of what was narrated from Ali (may Allah be pleased with him) regarding the bearers of the Throne and their description?

This book is not reliable due to its inclusion of fabricated (mawdu'ah) and weak (da'ifah) hadiths, among them the two mentioned hadiths, which have no basis and are falsely attributed to the Prophet, peace and blessings be upon him. Therefore, it should not be relied upon, nor should similar books that gather both the good and the bad. Scholars have served the hadiths of the Messenger, peace and blessings be upon him, distinguishing the sound from the unsound. Thus, a believer should acquire good and beneficial books such as the Two Sahihs (Bukhari and Muslim), the four Sunan books, Muntaka al-Akhbar, Riyad al-Salihin, Bulugh al-Maram, and Umdat al-Hadith.
