שפתיו דובבות בקבר is a chazal that you are unaware of. It applies talmidei chachomim that are בקבר yet their lips are MOVING! If someone’s lips are moving – is that person dead? Define dead?!
Rebbetzin,
Is it your contention then that the widow of a talmid chochom cannot re-marry because her husband’s lips move in the kever, proving that he is, in fact, still alive?
