Q 3: What is
the Islamic ruling on one who habitually curses?
He curses his children and other things. He is now old and still continues to do this?
It is not permissible for a Muslim to curse his children or any other thing. The person who does so should repent to Allah (Glorified and Exalted be He) and seek His Forgiveness. If he persists, he would be considered a sinner.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
