Muhammad ibn Ubayd ibn Abu Salih who lived in Ayliya said: I went out with Adi ibn Adi al-Kindi till we came to Makkah. He sent me to Safiyyah daughter of Shaybah who remembered a tradition (that she had heard) from Aishah. She said: I heard Aishah say: I heard the Messenger of Allah ﷺ say: There is no divorce or emancipation in case of constraint or duress (ghalaq). Abu Dawud said: I think ghalaq means anger.

Explanation & Benefits

Benefits and Issues:
In the books of Gharib al-Hadith, the meanings of "ighlaq" include compulsion, coercion, and insanity.
In this hadith, what is meant is that intense state of anger in which a person loses awareness.
Otherwise, in normal circumstances, no one gives divorce out of happiness.
If divorce is forced through compulsion or coercion, or if someone gives divorce in a state of insanity, it is not valid.
If it is given in anger, then it does take effect.
