Sunan Abi Dawud, 4486
sahih· Al-Albani

’Ali said:

I shall not pay blood-money or (he said) : I am not going to pay blood-money for him on whom I inflicted the prescribed punishment except for the one who drank wine, for the Messenger of Allah (ﷺ) did not prescribe anything definite. It is a thing which we have decided (by agreement) ourselves.

حَدَّثَنَا إِسْمَاعِيلُ بْنُ مُوسَى الْفَزَارِيُّ، حَدَّثَنَا شَرِيكٌ، عَنْ أَبِي حُصَيْنٍ، عَنْ عُمَيْرِ بْنِ سَعِيدٍ، عَنْ عَلِيٍّ، رضى الله عنه قَالَ لاَ أَدِي - أَوْ مَا كُنْتُ لأَدِيَ - مَنْ أَقَمْتُ عَلَيْهِ حَدًّا إِلاَّ شَارِبَ الْخَمْرِ فَإِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم لَمْ يَسُنَّ فِيهِ شَيْئًا إِنَّمَا هُوَ شَىْءٌ قُلْنَاهُ نَحْنُ ‏.‏
