What is the ruling on not alerting colleagues to an error in a book they were advised to read, which describes Prophet Jacob (peace be upon him) as a "skeptical and anxious personality" based on verses from Surat Yusuf, and is one absolved of responsibility without this alert?

What the author of the book mentioned about the Prophet of God, Jacob, combines ill-manners and a misunderstanding of his story and character. His prohibition to his son Joseph from narrating his vision to his brothers, and his fear of sending him with them, was motivated by his knowledge of the devil’s stratagems. Similarly, his command to his sons to enter separately was motivated by his knowledge that the evil eye is real, and not mere suspicion.

Suspicion based on strong evidence is not blameworthy; rather, it is a praiseworthy form of prudence. Jacob, peace be upon him, was a man of knowledge, not an anxious, suspicious person. Therefore, we do not recommend reading this book due to its offense, and any good it contains can be dispensed with by other books that have addressed the story without offense.
