Cursing people

Q 4: Does a man have the right to curse people and invoke Satan's curse on them? Does a man have the right to curse and insult his wife or to invoke (Part No. 26; Page No. 64) curse, anger or shame on her?

A: This is not permissible with regard to a Muslim, whether they are a relative or not; rather, it is of the major sins, for the Prophet (peace be upon him) said, Abusing a Muslim is Fusuq (evil doing) and killing him is Kufr (disbelief). (Agreed upon by Al-Bukhari and Muslim.) And No man accuses another man of sin or Kufr, but it shall rebound on him, if his companion is not like that. (Reported by Al-Bukhari). May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
