Ferdinand accepted Muslim conversion when it happened on its own

Evidence

Forcible conversion of Muslims came at different times for the various kingdoms into which Spain in the sixteenth century was divided: first to suffer were the lands of the Crown of Castile in 1500–1502, then Navarre in 1515–16, and finally the lands of the Crown of Aragon (i.e., Catalonia, Aragon, and Valencia) in 1523–26. We will see that the historical circumstances were quite different in each case. — L. P. Harvey, Muslims in Spain, 1500 to 1614, 99 (#complicates, via linked claim)

Ramon de Penyafort studied law in Bologna (from 1210 to 1219) where he met Dominic; he became a Dominican in 1222. Ramon served as confessor and chaplain to Pope Gregory IX from 1230 to 1238, then served as master general of the Dominicans from 1238 to 1240. Most of the rest of his life he spent in Barcelona, where, as spiritual adviser to Jaume I, he convinced the king to establish an inquisition in Aragon and to give his backing to the evangelical activities of his team of Dominican missionaries. In the last thirty-five years of his life, Ramon rallied royal and papal support for the establishment of language schools for missionaries, for the obligatory attendance of Muslims and Jews at the friars’ missionary sermons. — John V.

What was new in the situation at this time was that those Muslims who surrendered and wished to stay on in their homes were only permitted to do so if they were willing to accept conversion to Christianity. The Muslim masses seem to have done this, although it is impossible to speak to their hidden inner motivation. — L. P. Harvey, Muslims in Spain, 1500 to 1614, 214 (#complicates, via linked claim)
