Ubaydullah bin Abdullah bin Utba reported,

Umar bin Khattab asked Abu Waqid Laythi, "What did the Messenger of Allah ﷺ recite on the day of Fitr and the day of Adha?"He replied, "He used to recite 'Qaf. By the glorious Quran' [Qaf 50:1] and 'The Hour has drawn near, and the moon has split' [Qamar 54:1]."
