they did not form any proper estimate of allah when they said allah has not revealed anything to any man. ask them the book which moses brought as a light and guidance for men and which you keep in bits and scraps some of which you disclose while the rest you conceal even though through it you were taught that which neither you nor your forefathers knew who was it who revealed it? say allah! and then leave them to sport with their argumentation.
وما قدروا الله حق قدره إذ قالوا ما أنزل الله على بشر من شيء قل من أنزل الكتاب الذي جاء به موسى نورا وهدى للناس تجعلونه قراطيس تبدونها وتخفون كثيرا وعلمتم ما لم تعلموا أنتم ولا آباؤكم قل الله ثم ذرهم في خوضهم يلعبون
