Brief sunnahs before Fajr

عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ كَانَ النَّبِيُّ صلى الله عليه وسلم يُخَفِّفُ الرَّكْعَتَيْنِ اللَّتَيْنِ قَبْلَ صَلاَةِ الصُّبْحِ حَتَّى إِنِّي لأَقُولُ هَلْ قَرَأَ بِأُمِّ الْكِتَابِ

Hazrat Aishah^ra relates: “The Prophet^sa used to pray the two rakʿahs that precede the Fajr prayer so lightly that I would wonder to myself, ‘Did he even recite Surah al-Fatihah? [I.e., the two raka‘ahs were so concise that it felt almost imperceptible.]’”

(Sahih al-Bukhari, Kitab at-tahajjud, Bab ma yuqra’u fi rak`atay al-fajr, Hadith 1165)
