The pope authorized Charles V to break his oath not to force conversions

Evidence

In 1518 he had sworn not to force his Muslim subjects into conversion. The Vatican was consulted, and on November 3, 1525, Charles was able to write to the inquisitor-general enclosing the papal brief that authorized him to retract those of his promises that concerned the Muslims (not the rest of his promises, of course! Lea 1901, 139). — L. P. Harvey, Muslims in Spain, 1500 to 1614, 467
