ذِكْرُ مَا يُسْتَحَبُّ لِلْمَرْءِ التَّخْفِيفُ فِي رَكْعَتَيِ الْفَجْرِ إِذَا رَكَعَهُمَا
The Prophet ﷺ would pray two rak'ahs before the dawn prayer lightly so much so that I would say: Did he recite Surah al-Fatihah in them. (Using translation from Abū Dāʾūd 1255)
«كَانَ النَّبِيُّ ﷺ لَيُصَلِّي رَكْعَتَيِ الْفَجْرِ فَيُخَفِّفُهُمَا حَتَّى إِنِّي لَأَقُولُ هَلْ قَرَأَ فِيهِمَا بِأُمِّ الْقُرْآنِ؟ »
