All the rules in real Islam of the Prophet and his Holy Progeny ( Ahlul Bayt) (SAWA) are based on the absolute wisdom for the benefit of human beings. Allah, His messenger and Ahlul Bayt, know the full reasons for every rule. We might know little bit but we firmly believe in the Absolute Wisdom, Knowledge and Mercy of Allah. That is why we do not argue and never question why after our faith in Allah's Mercy, Knowledge and Wisdom.

No doubt, divorce being the most unwelcome act, should not be given to woman who is more emotional than man. Islam aims to decrease chances of divorce being breaking the families. Conditions for valid divorce in Islam are many and not very easy to achieve immediately. The aim is to discourage emotional divorces.
