عَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُ قَالَ: رَمَقْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَقْرَأُ فِي الرَّكْعَتَيْنِ قَبْلَ الْفَجْرِ {قُلْ يَا أَيُّهَا الْكَافِرُونَ} وَ{قُلْ هُوَ اللَّهُ أَحَدٌ}
Sayyiduna Abdullah bin Umar (may Allah be pleased with him) says: I observed carefully that the Noble Prophet (peace and blessings be upon him) used to recite Surah Al-Kafiroon and Surah Al-Ikhlas in the two rak'ahs before the Fajr prayer.
