A question often arises regarding the ruling on mourning for kings and leaders upon their death. According to Sharia, there is no special mourning period for these individuals beyond what is prescribed for anyone else. Islam prescribes mourning for three days for any deceased person, except for a wife who mourns her husband for four months and ten days. Therefore, mourning for kings and leaders should follow the same rules as for others, and the prescribed Sharia guidelines should be observed.
