The Writing
Scholars have said that if a person sees themselves writing for themselves, it may indicate earning unlawful money. However, if one sees someone else writing on them, especially if the writer is known, it suggests deception or misguidance in faith. Engraving on a man's hand may be interpreted as a trick followed by humiliation, while for a woman, it could signify a trick to gain something.
Per Ibn Sirin's Muntakhab al-Kalam fi Tafsir al-Ahlam
