16ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عُثْمَانَ بْنِ عِيسَى قَالَ سَأَلْتُ أَبَا الْحَسَنِ مُوسَى (عَلَيْهِ السَّلام) عَنِ الْقِيَاسِ فَقَالَ مَا لَكُمْ وَالْقِيَاسَ إِنَّ الله لا يُسْأَلُ كَيْفَ أَحَلَّ وَكَيْفَ حَرَّمَ.
16. A number of our people has narrated from Ahmad ibn Muhammad from ‘Uthman ibn ‘Isa who has said the following: “I asked (Imam) Abu al-Hassan Musa عليه السلام about the use of analogy and the Imam said, ‘What do you have to do with analogy? Allah is not asked about how he made things lawful or unlawful.’”
