How many messengers and prophets prayed with the Prophet (peace and blessings be upon him) in Al-Aqsa Mosque on the night of Al-Isra, and is there a known chain of transmission regarding their number?

The number of prophets with whom the Prophet, peace and blessings be upon him, prayed on the Night Journey (Laylat al-Isra') in Al-Aqsa Mosque was not specified; they were mentioned collectively. As for the total number of prophets, it is one hundred and twenty-four thousand, among whom are three hundred and fifteen messengers, as stated in Musnad Imam Ahmad. Twenty-five of them are mentioned in the Holy Quran, and it is probable that all of them were present on the Night Journey and the Prophet, peace and blessings be upon him, led them in prayer.
