Baha’u’llah rarely compares his sufferings to those of Muhammad, preferring instead to parallel his mistreatment to that of Muhammad’s martyred grandson Husayn. But the comparison with Muhammad is apt if for no other reason than both men lived long lives as self-proclaimed prophets and died peacefully in their beds.
One of the few places Baha’u’llah makes the comparison is in the “Tablet of Tribulations,” written between 1863 and Baha’u’llah’s death in 1892. Here is my translation of the tablet (revised as of Sept. 28, 2016), along with the original Arabic and Persian text. Suggestions for improvement are very welcome.
