What is the ruling on praying over a deceased person while they are inside a covered coffin?

Scholars have differed regarding the validity of praying over the deceased inside a covered wooden coffin. Some have validated it absolutely, some have prohibited it absolutely, and some have made distinctions. The root of this difference lies in the condition of the deceased's presence. It is more cautious not to pray over a wooden-covered coffin, even though the more preponderant opinion is the absolute validity of the prayer. This difference of opinion is specific to a wooden-covered coffin. As for an uncovered coffin or one covered with something other than wood, there is no issue concerning the validity of praying over it.
