This is absolutely devastating & unprecedented here. A Sunni Muslim man has been arrested as the primary suspect in the killings of four Muslim men - three of whom were Shia and one Sunni. The motive is believed to be anti-Shia: his daughter married a Shia man.
We recall the sacrifice of Imam Hussain (AS). For him, there was nothing more important than the values of truth and justice. His emphasis on equality as well as fairness are noteworthy and give strength to many.
