Hadith.864 - Hafs ibn al-Bakhtari narrate from Imam Jafar ibn Muhammad Al-Sadiq عليه السلام : "When the Messenger of Allah صلى الله عليه وعلى آله وسلم was taken on the night journey (Isra'), the time for prayer arrived, and Archangel Jibril عليه السلام called the adhan (call to prayer). When He said 'Allahu Akbar, Allahu Akbar' (Allah سبحانه وتعالى is the Greatest, Allah سبحانه وتعالى is the Greatest), the angels said 'Allahu Akbar, Allahu Akbar.' When He said 'Ashhadu an la ilaha illallah سبحانه وتعالى' (I bear witness that there is no god but Allah سبحانه وتعالى), the angels said: 'He has renounced rivals (associating others with Allah سبحانه وتعالى).' When He said 'Ashhadu anna Muhammadan Rasulullah' (I bear witness that Muhammad is the Messenger of Allah صلى الله عليه وعلى آله وسلم), the angels said: 'A Prophet has been sent.' When He said 'Hayya 'ala as-Salah' (Come to prayer), the angels said: 'He calls to the worship of his Lord عز وجل.' When He said 'Hayya 'ala al-Falah' (Come to success), the angels said: 'Success is for the one who follows him.'".
