What is the ruling on saying "La ilaha illa Allah" and reciting Surat Yasin during the burial of the deceased?

Question:
The questioner says: We notice that when we go to the cemetery to bury some of the deceased, some Muslims say "Wahdahu" (He is One), and most of them say "La ilaha illa Allah," and some of them recite Surat Yasin over the deceased. We ask you to point this out, may Allah reward you.

Answer:
All of these matters are religious innovations (bid'ah): saying "Wahdahu," raising the voice with "La ilaha illa Allah," and reciting the Qur'an. All of this is bid'ah. What evidence is there for this? The one who accompanies the funeral procession walks with calmness, makes du'a' for the deceased, does not raise his voice, and participates in burying him if he is able. When the burial is finished, he stands at the grave, seeks forgiveness for him, and asks Allah to grant him steadfastness. This is what was reported from the Messenger (peace and blessings be upon him).
