Recitation in the first two rak'ahs of 'Asr
Sunan an-Nasai
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."
