فَإِنْ أَخَّرَهُ عَنْهَا لَزِمَهُ دَمٌ عِنْدَ أَبِي حَنِيفَةَ.
Translation: If he delays it beyond those days, a sacrificial dam becomes due according to Abu Hanifah.
Lazimahu damun means a prescribed sacrificial compensation becomes due for the relevant delay; dam here is not a medical reference to blood.
Under Abu Hanifah, the pilgrim has failed to observe the required timing, which entails dam. Yet the obligatory tawaf still must be performed. Genuine impediments—including some menstrual or medical circumstances—require their own detailed analysis.
