The Book (Empty)
Interpreters mention that whoever sees a book or a Mushaf in their hand in a dream, and then opens it to find no writing inside, it may indicate that their outward appearance contradicts their inner reality. This vision is interpreted as a warning against hypocrisy or a lack of sincerity between words and actions.
Per Ibn Sirin's Muntakhab al-Kalam fi Tafsir al-Ahlam
