Brief Explanation
(Explanation of Hadiths 1479 to 1483) From all these narrations, it is established to perform two rak‘ahs of Sunnah before the Fajr prayer. Also, it is evident that the Prophet sallallahu alayhi wa sallam used to perform these Sunnahs lightly, and after Surah al-Fatihah, he would recite «﴿قُلْيَاأَيُّهَاالْكَافِرُونَ﴾» in the first rak‘ah and «﴿قُلْهُوَاللّٰهُأَحَدٌ﴾» in the second rak‘ah.
