وَمَنْ أَخَّرَ الْحَلْقَ حَتَّى مَضَتْ أَيَّامُ النَّحْرِ: فَعَلَيْهِ دَمٌ عِنْدَ أَبِي حَنِيفَةَ.
Translation: Whoever delays shaving until the sacrifice days have ended owes dam according to Abu Hanifah.
This is a violation by delay rather than complete omission. The text explicitly attributes the penalty for delaying shaving beyond the prescribed sacrifice days to Abu Hanifah.
Do not present this attribution as if the cited sentence expressed an undifferentiated consensus of all jurists.
