سورة الفرقان

Imam Baqir (peace be upon him): وَ قالُوا أَساطِیرُ الْأَوَّلِینَ اکْتَتَبَها [And they say: Tales of the ancients which he has had written down] — this is the statement of Nadr ibn Harith ibn Alqama Kalada, who said: أَساطِیرُ الْأَوَّلِینَ [the tales of the ancients] is Muhammad (peace be upon him and his family). اکْتَتَبَها، فَهِیَ تُمْلی عَلَیْهِ بُکْرَةً وَ أَصِیلًا [he has had them written down, and they are dictated to him morning and evening].

Ali ibn Ibrahim: "You did not recite any book before this, nor did you write one with your right hand, lest those who seek to [reject and] invalidate your words should doubt." (Ankabut/48) This verse is like the verse in which the polytheists said: اکْتَتَبَها فَهِیَ تُمْلی عَلَیْهِ بُکْرَةً وَ أَصِیلًا [he has had them written down, and they are dictated to him morning and evening]. Allah said concerning their thinking: "How do you say concerning that which the Prophet (peace be upon him and his family) recites and by which he informs, that he has written it from another, while he never recited any book before this, nor wrote anything with his hand, lest those who seek to reject and invalidate his words should doubt." (Ankabut/48)

Ali ibn Ibrahim: They said, "What Muhammad (peace be upon him and his family) recites and informs us of, he learns from the Jews, and the Christian scholars write it for him, and a man called Ibn Qubayta narrates it to him every morning and evening." وَ قالَ الَّذِینَ کَفَرُوا إِنْ هَذا إِلَّا إِفْکٌ افْتَراهُ وَ أَعانَهُ عَلَیْهِ قَوْمٌ آخَرُونَ فَقَدْ جاؤُ ظُلْماً وَ زُوراً وَ قالُوا أَساطِیرُ الْأَوَّلِینَ اکْتَتَبَها فَهِیَ تُمْلی عَلَیْهِ بُکْرَةً وَ أَصِیلًا [And those who disbelieve say: This is nothing but a lie which he has forged, and other people have helped him with it; so indeed they have brought an injustice and a falsehood. And they say: Fables of the ancients — he has had them written down, so they are dictated to him morning and evening], and Allah has refuted them [in both statements]. O Muhammad (peace be upon him and his family), say to them: أَنْزَلَهُ الَّذِی یَعْلَمُ السِّرَّ فِی السَّماواتِ وَ الْأَرْضِ إِنَّهُ کانَ غَفُوراً رَحِیماً [He has revealed it Who knows the secret in the heavens and the earth; surely He is ever Forgiving, Merciful].
