Why is this terrorist attack in Sri Lanka (on the pretext of revenge) a surprise - given that the Prophet Muhammad himself murdered 900-1000 innocent people in one day in the systematic Genocide of the Banu Qurayza tribe. The only peaceful credentials shown by the merciful Prophet of Islam were that he sold the women and children into slavery for financial profit and kindly kept a few of the best looking women (whose fathers, husbands and brothers he had murdered) as personal sex slaves (since the rape of female sex slaves is permitted in the Holy Quran).
