وَيُكْرَهُ تَأْخِيرُهُ عَنْ هَذِهِ الْأَيَّامِ.
Translation: And delaying it beyond these days is disliked.
Hādhihi al-ayyām refers back to 10, 11 and 12 Dhu al-Hijjah. Al-Quduri calls delaying the visitation tawaf beyond these days disliked.
The text is not merely advising convenience: the next clause adds a dam penalty for delay under Abu Hanifah's ruling. The clauses must therefore be read together, including the legal treatment of genuine excuses.
