The Messenger of Allah ﷺ said, "Prayer in congregation is superior to a man's prayer alone by twenty-five degrees, and the angels of the night and the angels of the day gather together at the Fajr prayer."Then Abu Hurairah would say, "Recite if you wish, 'And the recitation of dawn. Indeed, the recitation of dawn is ever witnessed'" [Isra 17:78].
حدثنا عبد الأعلى عن معمر عن الزهري عن سعيد بن المسيب
أن رسول الله ﷺ قال تفضل الصلاة في الجميع على صلاة الرجل وحده خمسا وعشرين ويجتمع ملائكة الليل وملائكة النهار في صلاة الفجر ثم يقول أبو هريرة اقرءوا إن شئتم {وقرآن الفجر إن قرآن الفجر كان مشهودا}
Its isnad is sahih. Muslim related it, 1:180, from Abu Bakr bin Abu Shayba, from Abdul-Ala, with this isnad. Then he related it via Shuayb, from Zuhri, from Saeed bin Musayab and Abu Salama, from Abu Hurairah, in a similar wording. Bukhari likewise related it, 2:115, via Shuayb. Bukhari also related it, 302, via Abdul-Razzaq, from Maamar, from Zuhri, from Abu Salama and Ibn Musayab, from Abu Hurairah. See also tafsir of Ibn Kathir, 2:125. See also what has already passed of the hadith of Abdullah bin Umar, 4670, 5332, 5921, 6455.
