Is the book "Bihar al-Anwar" authentic and supported by a chain of transmission (musnad)? Is "Tafsir al-Jalalayn" by Imam al-Suyuti a reliable book supported by a chain of transmission (musnad)? And is Imam al-Suyuti considered a scholar among the people of Sunnah and Jama'ah?

Bihar al-Anwar is a Twelver Shiite book full of fabrications and misguidance. As for Tafsir al-Jalalayn, it is good and concise, but it contains some errors related to the attributes of Allah and matters of belief according to its Ash'ari madhhab. One can benefit from the book Anwar al-Hilalayn fi al-Ta'aqqubat 'ala al-Jalalayn to correct these errors. Sheikh Ibn Baz praised it, while also pointing out its errors regarding the attributes.
