What is the ruling on a father who does not provide for his children, despite being well-off and capable of securing a decent life for them, especially given the cramped conditions of their two-room dwelling for seven individuals aged between 18 and 24 years?

Scholars have differed regarding a father's financial support for his adult, able-bodied son. The majority view is that it is not obligatory. However, Sheikh al-Islam Ibn Taymiyyah held the view that it is obligatory if the son is poor and unable to earn, and the father is wealthy. A father's financial support for his daughter is obligatory until she marries, due to her inability to earn a living. A father is not obligated to spend on his sons unless they are poor and unable to earn, or if they are engaged in education. As for daughters, the father is obligated to spend on them until marriage. The father must provide appropriate food, clothing, and housing for those whom he is obligated to support. He is also obligated to marry off his sons if they desire it and he is able. It is permissible for children to take their maintenance from their father's wealth without his knowledge if he refuses to provide it, based on the hadith of Hind, the wife of Abu Sufyan.
