فَإِذَا كَانَ مِنَ الْغَدِ رَمَى الْجِمَارَ الثَّلَاثَ بَعْدَ زَوَالِ الشَّمْسِ كَذَلِكَ
Translation: On the next day, he likewise stones all three Jamarahs after the sun has passed the meridian.
Min al-ghad here means 12 Dhu al-Hijjah. Kadhālik repeats the preceding day's sequence: all three Jamarahs, seven pebbles each, and supplication after the first two.
Al-Quduri again explicitly says after zawāl. His later concession for 13 Dhu al-Hijjah must not be generalized to the 12th.
