[Machine] I heard the Messenger of Allah, ﷺ , say that the angels of the night and the angels of the day gather at the Fajr prayer. Then Abu Hurayrah said, "Read if you wish: 'And recite the Qur'an at Fajr. Verily, the recitation of Fajr is witnessed.'" This is mentioned in Sahihain from the Hadith of Abu Al-Yaman.
سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ يَجْتَمِعُ مَلَائِكَةُ اللَّيْلِ وَمَلَائِكَةُ النَّهَارِ فِي صَلَاةِ الْفَجْرِ ثُمَّ يَقُولُ أَبُو هُرَيْرَةَ اقْرَءُوا إِنْ شِئْتُمْ {وَقُرْآنَ الْفَجْرِ إِنَّ قُرْآنَ الْفَجْرِ كَانَ مَشْهُودًا} [الإسراء 78] مُخَرَّجٌ فِي الصَّحِيحَيْنِ مِنْ حَدِيثِ أَبِي الْيَمَانِ
