From Sahih Muslim (Hadith 2059):
Abdullah b. 'Umar reported that (his father) 'Umar b. Khattab asked Abu Waqid al-Laithi what the Messenger of Allah (ﷺ) used to recite on 'Id-ul-Adha and 'Id-ul-Fitr. He said:He used to recite in them:" Qaf. By the Glorious Qur'an" (Surah 1)," The Hour drew near, and the moon was rent asunder" (Surah liv)
