The Prophet ﷺ used to pray Zuhr when the sun had passed its zenith.
حدثنا محمد بن بشار حدثنا يحيى بن سعيد عن شعبة عن سماك بن حرب
أن النبي ﷺ كان يصلي الظهر إذا دحضت الشمس
Muslim recorded it in the Book of Mosques, in the chapter on the recommendation of praying Dhuhr at the beginning of its time when there is no extreme heat, hadith no. 618, from Ibn Bashar and others, with this same chain.
