AhadithA'ashura ‑ A Day of Grief


قال الرضا (ع):
مَن كان يوم عاشوراء يوم مُصيبته وحُزنه وبُكائه يجعل الله عزَّ وجل يوم القيامة يوم فرحه وسروره

Imam Ridha’ (A.S.) said

The one for whom the day of A'ashura is a day of tragedy, grief and weeping, Allah The Mighty, The Glorious, shall make the Day of Judgment, a day of joy and happiness for him.
