Recitation in the first two rak'ahs of 'Asr
أَخْبَرَنَا إِسْحَاقُ بْنُ مَنْصُورٍ، قَالَ حَدَّثَنَا عَبْدُ الرَّحْمَنِ، عَنْ شُعْبَةَ، عَنْ سِمَاكٍ، عَنْ جَابِرِ بْنِ سَمُرَةَ، قَالَ كَانَ النَّبِيُّ صلى الله عليه وسلم يَقْرَأُ فِي الظُّهْرِ { وَاللَّيْلِ إِذَا يَغْشَى } وَفِي الْعَصْرِ نَحْوَ ذَلِكَ وَفِي الصُّبْحِ بِأَطْوَلَ مِنْ ذَلِكَ .
It was narrated that Jabir bin Samurah said: "The Prophet (ﷺ) used to recite "By the night as it envelops" in Zuhr and something similar in 'Asr, and he would recite something longer than that in subh."
