What rights does a girl or woman have when facing verbal, emotional, or physical abuse from her in-laws? What guidance do the Quran, Hadith, and Ahlulbayt provide regarding the expected behavior of in-laws towards their daughters-in-law?
Quran, the Prophet (SAWA) and Ahlul Bayt (AS) have clearly ordered every Muslim to be just and fair when dealing with others. Talk to people in nice way. (Sura 2, verse 83). Prophetic Hadeeth orders us: Deal with people in the same way which you want them to deal with you, and talk to them in the same way that you want them to talk to you. No one is allowed to verbally, emotionally, physically abuse others. Such abuse can be a major sin.
This is a general Islamic rule which is obligatory in all Muslims when they deal any other person.
Wassalm.
