فَإِنْ قَدَّمَ الرَّمْيَ فِي هَذَا الْيَوْمِ قَبْلَ الزَّوَالِ بَعْدَ طُلُوعِ الْفَجْرِ جَازَ عِنْدَ أَبِي حَنِيفَةَ رَحِمَهُ اللَّهُ
Translation: If on that fourth day he advances the stoning to after dawn but before zawāl, it is permissible according to Abu Hanifah, may Allah have mercy on him.
Fī hādhā al-yawm refers back to the fourth day counted from the Sacrifice Day, namely 13 Dhu al-Hijjah. For this particular date, Al-Quduri records Abu Hanifah's permission to stone after dawn but before zawāl.
This exception cannot be extended to the mornings of 11 or 12 Dhu al-Hijjah. After zawāl remains the stated regular manner even on the 13th.
