Evidence

In the seta San Pedro summed the position up thus: Muhammad had rightly said that we should attribute the good in us to God alone, and quite wrongly that good and evil alike ‘proceed from God’ (1.ii.9; cf. CFM vur.2). See CFM, part vir passim; part vin for the whole subject. Inconsistency with O.T.: see CFM 11.2ff and Exod. xx. and cf. Watt, loc. cit. — Norman Daniel, Islam and the West, 2226
