The Book in the Right Hand
Scholars have said that whoever sees their book in their right hand, this is a sign of goodness, ease, and relief in their affairs. If they are in a dispute, clarification will come; if worried or absent, their affairs will ease, and they will return joyful. Conversely, giving the book with the left hand may indicate regret.
