'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).  

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 }
