What Should Be Recited In (The Two 'Eid Of) Al-Adha And Al-Fitr

'Ubaid Allah b. 'Abd Allah b. 'Utbah b. Mas'ud said:
'Umar b. al-Khattab asked Abu Waqid al-Laithi: What did the Messenger of Allah ﷺ recite during the prayer on the day of sacrifice and on the breaking of the fast ? He replied: He recited at both of them Surah al-Qaf, "By the Glorious Quran" [50] and the Surah "The Hour is nigh" (54).

حَدَّثَنَا الْقَعْنَبِيُّ، عَنْ مَالِكٍ، عَنْ ضَمْرَةَ بْنِ سَعِيدٍ الْمَازِنِيِّ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ بْنِ عُتْبَةَ بْنِ مَسْعُودٍ، أَنَّ عُمَرَ بْنَ الْخَطَّابِ، سَأَلَ أَبَا وَاقِدٍ اللَّيْثِيَّ مَاذَا كَانَ يَقْرَأُ بِهِ رَسُولُ اللَّهِ ﷺ فِي الأَضْحَى وَالْفِطْرِ قَالَ كَانَ يَقْرَأُ فِيهِمَا { ق وَالْقُرْآنِ الْمَجِيدِ } وَ { اقْتَرَبَتِ السَّاعَةُ وَانْشَقَّ الْقَمَرُ } .
