He said: No, by the One who split the seed and created the soul, except the understanding that Allah, may He be glorified and exalted, helps a person to acquire of the Qurʿan or what is in the document.I said: What is in the document? He said: Diyah (blood money), ransom of prisoners and muslim should be killed in retaliation for a kafir.
سَأَلْنَا عَلِيًّا هَلْ عِنْدَكُمْ مِنْ رَسُولِ اللهِ ﷺ شَيْءٌ بَعْدَ الْقُرْآنِ؟ قَالَ لَا وَالَّذِي فَلَقَ الْحَبَّةَ وَبَرَأَ النَّسَمَةَ إِلا فَهْمٌ يُؤْتِيهِ اللهُ ﷻ رَجُلًا فِي الْقُرْآنِ أَوْ مَا فِي الصَّحِيفَةِ قُلْتُ وَمَا فِي الصَّحِيفَةِ؟ قَالَ الْعَقْلُ وَفِكَاكُ الْأَسِيرِ وَلا يُقْتَلُ مُسْلِمٌ بِكَافِرٍ
