Analysis of information sources in references of the Wikipedia article "Pindah agama paksa" in Indonesian language version.
‘No compulsion in religion’ (2:256) was a Qur'anic command revealed in Medina when a child from one of the Muslim families who had been educated in the town's Jewish schools decided to depart with the Jewish tribe being expelled from Medina. His distraught parents were told by God and the Prophet in this verse that they could not compel their son to stay. The verse, however, has been understood over the centuries as a general command that people cannot be forced to convert to Islam.
To begin with, there was no forced conversion, no choice between “Islam and the Sword”. Islamic law, following a clear Quranic principle (2:256), prohibited any such things [...] although there have been instances of forced conversion in Islamic history, these have been exceptional.
