He is in need and his brother is a music-writer
Question

                My brother works as a music-writer, putting music to songs, and he has no other source of income. I cannot work, and my father is dead. Is it permissible for me to eat from his wealth (be supported by him)?
Praise be to Allah.We put this question to Shaykh Muhammad ibn Saalih
    al-‘Uthaymeen, may Allaah preserve him, and he answered as follows:
Yes, it is permissible for you to eat from his
    wealth, so long as you are in need, and it is his duty to spend on you.
