The Holy Prophet (PBUH) is the behavioral role model of nation. People who were not identical with him both in attitudes and manners and they had their own specail morality and behavior publically insulted the Holy prophet peace be upon him and his progeny, but Allah commands in Sura Al Imran and said to Holy prophet: «فَاعْفُ عَنْهُم » (Al Imran/159) forgive them, it means leave the fight one sided, when the fight and dispute is one sided, the one who commenced the fight would regret his anger and feel sorry, then maybe the couples ask for forgiveness from each other.
