Narrated Abu Salama bin 'Abdur Rahman: Abu Huraira said, "I heard Allah's Messenger ﷺ saying, 'The reward of a prayer in congregation is twenty five times greater than that of a prayer offered by a person alone. The angels of the night and the angels of the day gather at the time of Fajr prayer'. " Abu Huraira then added, "Recite the Holy Book if you wish, for "Indeed, the recitation of the Qur'an in the early dawn (Fajr prayer) is ever witnessed". (17:78).
The Prophet Muhammad ﷺ taught his followers that coming together for prayer was an important part of being a Muslim and should be done regularly with sincerity and devotion. He said that those who do so will receive a great reward from Allah SWT which is far greater than what they would receive if they were to pray alone. Furthermore, he mentioned that during this time angels come down from Heaven and surround those who are praying in order to protect them and guide them on their path towards righteousness.
Finally, this hadith reminds us how important it is for Muslims to come together as one community united by faith in order to gain Allah's blessings through prayer and recitation of His words found within the Quran.
