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, may Allah bless
him and grant him peace, used to recite in the prayers of Adha and
Fitr. He said, "He used to recite Qaf (Sura 50) and al-lnshiqaq
(Sura84)."
