Ibn al Jawzi رحمه الله تعالى said:
"When your companion becomes angry and
says something that is unwarranted, you should not take it too hard. His
situation is that of a drunken person who is not aware of what is taking place.
Instead, be patient, even if it means only for a little while. If you
reciprocate his words with harsh words of your own, you become like the sane
person who seeks revenge on a madman, or the conscious person who seeks
retribution from an unconscious one. Look at him with a merciful eye and pity
him for his actions."
(Sayd
al-Khaatir pg. 406)
