عَنْ عَبْدِ اللَّهِ بْنِ شَقِيقٍ عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ كَانَ يَقُولُ: ((نِعْمَ السُّورَتَانِ هُمَا يُقْرَأُ بِهِمَا فِي الرَّكْعَتَيْنِ قَبْلَ الْفَجْرِ، {قُلْ يَا أَيُّهَا الْكَافِرُونَ} وَ{قُلْ هُوَ اللَّهُ أَحَدٌ}))
It is narrated from Sayyidah Aisha (may Allah be pleased with her) that the Noble Prophet (peace and blessings be upon him) said: The best surahs are those which are recited in the Sunnah prayers before the Fajr prayer, that is, Surah Al-Kafiroon and Surah Al-Ikhlas.
