تَدْعُونَهُ الْمُفَصَّلَ هُوَ الْمُحْكَمُ، قَالَ وَقَالَ ابْنُ عَبَّاسٍ تُوُفِّيَ رَسُولُ اللَّهِ صلى الله عليه وسلم وَأَنَا ابْنُ عَشْرِ سِنِينَ وَقَدْ قَرَأْتُ الْمُحْكَمَ.
Narrated Sa`id bin Jubair:
Those Suras which you people call the Mufassal, are the Muhkam. And Ibn `Abbas said, "Allah's Apostle died when I was a boy of ten years, and I had learnt the Muhkam (of the Qur'an).
Reported by Al-Bukhari (No. 5035) and Ahmad (No. 2169).
