Do we incur sin if innovations occur, such as announcing a death by loudspeaker, reciting Al-Fatiha collectively, reciting the Qur'an collectively, performing eulogies, lamenting, purchasing luxurious foods, boasting about burial rituals, and building over the grave during the funeral, burial, or mourning, even though we disapprove and know that the deceased would not approve, while these are the beliefs of the townspeople? And what should we do about that?

The deceased is not burdened by the sin of the innovated actions performed by their family after their death, unless they enjoined them or did not forbid them despite knowing that they would perform them. The proof for this is the hadith: "Indeed, the deceased is tormented by the weeping of their family over them." As for the sin, it falls upon those who commit these actions. It is incumbent upon the family of the deceased to denounce these innovations by hand, tongue, or heart, according to their ability, while choosing the most appropriate method. Announcing a death (na'i) is permissible if it is for informing about the prayer and burial, without enumerating virtues or boasting.
