سنن أبي داود#4624Sahihحَدَّثَنَا ابْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ قَالاَ حَدَّثَنَا مُؤَمَّلُ بْنُ إِسْمَاعِيلَ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنِ ابْنِ عَوْنٍ، قَالَ لَوْ عَلِمْنَا أَنَّ كَلِمَةَ، الْحَسَنِ تَبْلُغُ مَا بَلَغَتْ لَكَتَبْنَا بِرُجُوعِهِ كِتَابًا وَأَشْهَدْنَا عَلَيْهِ شُهُودًا وَلَكِنَّا قُلْنَا كَلِمَةٌ خَرَجَتْ لاَ تُحْمَلُ .

Scholarly Authentication
The label above is the grade most of these scholars gave, each scholar counted once — one dissenting opinion no longer speaks for all of them.

Each scholar's own wording:
