Yahya related to me from Malik from Damra ibn Said al-Mazini from Ubaydullah ibn Abdullah ibn Utba ibn Masud that Umar ibn al-Khattab asked Abu Waqid al-Laythi what the Messenger of Allah ﷺ used to recite in the prayers of Adha and Fitr. He said, "He used to recite Qaf (Sura 50) and al-lnshiqaq (Sura84)."
أَنَّ عُمَرَ بْنَ الْخَطَّابِ سَأَلَ أَبَا وَاقِدٍ اللَّيْثِيَّ مَا كَانَ يَقْرَأُ بِهِ رَسُولُ اللَّهِ ﷺ فِي الأَضْحَى وَالْفِطْرِ فَقَالَ كَانَ يَقْرَأُ بِ ق وَالْقُرْآنِ الْمَجِيدِ وَ اقْتَرَبَتِ السَّاعَةُ وَانْشَقَّ الْقَمَرُ
