Day of Sorrow
The Day of Sorrow (Persian: روز غم Ruz-e Gham, Urdu: یوم غم Yaum-e Gham) is commemorated by some Muslims, marking the razing of the Al-Baqi' cemetery in Medina by Saudi King Abdulaziz ibn Saud. The cemetery housed the bodies of many of the Ahl al-Bayt, members of the family of Muhammad, who are especially revered by Shia Muslims and play a central role in Shia Islamic theology.
