What is required for stoning a person who cursed their parent?
Capital liability for cursing a parent requires that one of God's unique, ineffable names be used. Using a euphemistic reference to God results only in lashes.
Question 2
A son who is a doctor amputates a limb from his suffering father when no other doctor is available. What is the law?
When no other person is available and the parent suffers, the son may act as a doctor according to the permission the parent grants. Rambam notes, however, that ideally someone else should perform the procedure.
Question 3
A son strikes his father on the ear and causes deafness. Is he liable?
It is halachically impossible to cause deafness without internal bleeding in the ear. Thus the wound required for liability is presumed to have occurred, and he is liable.
Question 4
What is the rule when parents are sentenced to death and their son strikes them?
If the parents repented, even while being taken to execution, the son is still liable if he strikes or curses them. Without repentance, he is not liable — but it is still forbidden.
Question 5
When is a son permitted to serve as a court agent to lash his own father?
In the case of a father who entices others to idol worship, the Torah explicitly states 'do not have pity and do not cover up' — overriding the normal prohibition on acting against one's parents.
