Is asking a deceased person for supplication considered major shirk (associating partners with Allah), or is it merely one of the forbidden religious innovations (bid'ah)?

Question:
May Allah reward you, Honorable Shaykh. This questioner asks: Is asking a deceased person for supplication, by saying to the deceased, "Pray to Allah for me," considered major shirk (associating partners with Allah), or is it merely one of the forbidden religious innovations (bid'ah)?

Answer:
We say that it is not permissible to ask a deceased person for anything, absolutely, whether it is supplication or anything else. This is sufficient for us; this is sufficient for us: that it is not permissible to ask a deceased person, because his deeds have ended, and because the Companions did not ask the Prophet (peace and blessings be upon him) to pray for rain for them; they turned to al-Abbas instead. Yes.
