The Meccan Revelations: Page 520 from Volume One

The ignorant dead and the ignorant dead, so the scholar must teach the ignorant, because part of the ignorance of the ignorant is that he does not know that it is obligatory for him to ask about what he does not know, so it is obligatory for the scholar to teach him that whoever does not know the ruling of Sharia regarding his movements must ask the people of remembrance, and if he does not do that, he has disobeyed, and teach him what he must be taught. That is his purity, and this is the washing of the dead in brief.
