Doctor Selling Shrouds
Scholars have said that whoever sees a doctor selling shrouds should beware of him, as it may indicate that he is a shedder of blood and treacherous in his practice. If the shrouds are folded, it may be a stronger indication of his deception in medicine and people's errors regarding him.
