the intercalation is but one more instance of refusal to acknowledge the truth by which those who are bent on denying the truth are led astray. they declare this to be permissible in one year and forbidden in year in order to conform to the number of months which god has hallowed and thus they make allowable what god has forbidden. goodly seems unto them the evil of their own doings since god does not grace with his guidance people who refuse to acknowledge the truth.
إنما النسيء زيادة في الكفر يضل به الذين كفروا يحلونه عاما ويحرمونه عاما ليواطئوا عدة ما حرم الله فيحلوا ما حرم الله زين لهم سوء أعمالهم والله لا يهدي القوم الكافرين
