عَنْ أَبِي جُحَيْفَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ سَأَلْنَا عَلِيًّا رَضِيَ اللَّهُ عَنْهُ هَلْ عِنْدَكُمْ مِنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ شَيْءٌ بَعْدَ الْقُرْآنِ قَالَ لَا وَالَّذِي فَلَقَ الْحَبَّةَ وَبَرَأَ النَّسَمَةَ إِلَّا فَهْمٌ يُؤْتِيهِ اللَّهُ عَزَّ وَجَلَّ رَجُلًا فِي الْقُرْآنِ أَوْ مَا فِي الصَّحِيفَةِ قُلْتُ وَمَا فِي الصَّحِيفَةِ قَالَ الْعَقْلُ وَفِكَاكُ الْأَسِيرِ وَلَا يُقْتَلُ مُسْلِمٌ بِكَافِرٍ
It is narrated from Sayyiduna Abu Hujayfah (may Allah be pleased with him), he says: We asked Sayyiduna Ali (may Allah be pleased with him) whether the Messenger of Allah (peace and blessings be upon him) gave you anything besides the Holy Qur'an? He said: No, by Him Who split the grain and created the soul! He gave us nothing except the understanding and insight which Allah grants to a man in the Qur'an, or that which is in this scroll. I asked: What is in it? He said: The issues of blood money (diyah), freeing a captive, and that a Muslim will not be killed in retaliation for a disbeliever.
