Is the narration of historical events in Ibn Kathir's book "Al-Bidayah wa al-Nihayah" definitively confirmed, or is there leniency in the relied-upon narrations, especially since the primary purpose is storytelling and not jurisprudential rulings? And can a jurisprudential stance be built upon a storytelling book by Ibn Kathir and Ibn Jarir? And what is the extent of the authenticity of Ibn Jarir's narrations in storytelling, especially regarding what was reported about Abdul Rahman ibn Auf consulting women and children in the selection of Uthman, knowing that other hadith books mention that the consultation was with the people of Badr and the senior Companions?
