A Series of Reminders About The Month of Muḥarram – No.9
Making The Day Of ‘Ashūrā’ A Day Of Mourning Is An Innovation
Sh. Ibn Bāz رحمه الله said: “As for making the day of ‘Ashūrā’ a day of mourning, then it is a despicable innovation which the Rāfīḍah have innovated.
By [introducing] it, they have opposed Ahl al-Sunnah Wa-al-Jamā’ah and what the Prophet ﷺ companions traversed upon.
Therefore, it is not permissible to resemble them in that.
