عَنْ أُمِّ هِشَامٍ بِنْتِ حَارِثَةَ بْنِ النُّعْمَانِ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: مَا أَخَذْتُ {قٓ وَالْقُرْآنِ الْمَجِيدِ} إِلَّا مِنْ وَرَاءِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ، كَانَ يُصَلِّي بِهَا فِي الصُّبْحِ
Umm Hisham bint Harithah bin Nu'man (may Allah be pleased with her) says: I did not memorize Surah Qaf except while standing behind the Noble Prophet (peace and blessings be upon him), because he (peace and blessings be upon him) used to recite it in the Fajr prayer.
