Sahih al-Bukhari Book 65, Hadith 240
On the Day of Resurrection the people will fall on their knees and every nation will follow their
prophet and they will say, "O so-and-so! Intercede (for us with Allah), "till (the right) intercession is
given to the Prophet (Muhammad) and that will be the day when Allah will raise him into a station of
praise and glory (i.e. Al-Maqam -al-Mahmud).
Abu Huraira said, "The Prophet (ﷺ) said, 'A prayer performed in congregation is twenty-five times more superior in reward to a prayer performed by a single person. The angels of the night and the angels of the day are assembled at the time of the Fajr (Morning) prayer." Abu Huraira added, "If you wish, you can recite:-- 'Verily! The recitation of the Qur'an in the early dawn (Morning prayer) is ever witnessed (attended by the angels of the day and the night).' (17.78)
Allah's Messenger (ﷺ) said, "Whoever, after listening to the Adhan (for the prayer) says, 'O Allah, the Lord of this complete call and of this prayer, which is going to be established! Give Muhammad Al-Wasila and Al-Fadila and raise him to Al-Maqam-al-Mahmud which You have promised him,' will be granted my intercession for him on the Day of Resurrection."
