„Shahjahan was even otherwise interested in making converts. Professor Sri Ram Sharma has collected facts and figures of Hindus converted to Islam from the works of Qazvini, Lahori, Salih, Mohsin Fani, Khafi Khan, etc. during Shajahan’s reign... The following is the summary of what he says. “Early in his reign Shahjahan had appointed a Superintendent of converts to Islam, thus setting up a department for the special purpose of making converts. The one common practice was to make terms with the criminals… The Hindus of the Punjab, Bhimbar, Bhadauri and Sirhind… were all offered remission of their sentences provided they accepted the ‘true faith’. When the war with the Portuguese started, of the 400 prisoners taken a few became Muslims. The rest were kept in prison with orders that whenever they expressed willingness to embrace Islam, they were to be converted, liberated and given daily allowances. An order was issued in the seventh year of his reign that if a Hindu wanted to be converted to Islam, his family should not place any obstacles in his way… Under Shahjahan, apostasy from Islam had again become a capital crime.”“
