Is it permissible to beat one's chest on the Day of Ashura and other days, by analogy with Jacob's grief over Joseph?

What the Shiites do on Ashura, such as beating chests and cheeks and shedding blood, is an innovation that has no basis in Islam, and it is a reprehensible act that the Prophet (peace be upon him) forbade, saying: «He is not one of us who slaps cheeks, tears garments, and calls with the call of the days of ignorance.» The Prophet (peace be upon him) did not do that upon the death of any of his Companions, nor did any of the Companions do it upon his death or the death of others.

Al-Hafiz Ibn Kathir explained that what the Shiites do by showing anguish and sorrow contains pretense and hypocrisy, for the Prophet (peace be upon him) and the Companions, who are superior to Hussein, did not have their death days turned into mourning ceremonies. Indeed, the Rafidha exaggerated during the Buyid state in displaying sorrow and committing heinous innovations on Ashura, while the Nawasib countered them by making it a day of Eid and joy.

Both celebrating Ashura or making it a mourning ceremony are innovations, as Ibn Taymiyyah said that Satan introduced two innovations: sorrow and wailing, and joy and happiness, and both are misguidance.

It is observed that these reprehensible acts are encouraged by the enemies of Islam to distort its image. Some historians mention that the British exploited the ignorance of the Shiites and their love for Imam Hussein to teach them to strike themselves with swords and chains, in order to present them as savages in need of a guardian. This explains the images and videos of violence that were published in Western newspapers to justify colonialism under the pretext of "humanitarian duty."
