question #3 Sahih al-Bukhari 2211, Book 34, Hadith 157 : What are the conditions under which one may take money from a family member according to Islamic teachings?

Hind, the mother of Mu’awiya said to Allah’s Messenger (ﷺ), “Abu Sufyan (her husband) is a miser. Am I
allowed to take from his money secretly?” The Prophet (ﷺ) said to her, “You and your sons may take what
is sufficient reasonably and fairly.”
