21. My father, may Allah grant him mercy, said: We were told by Ali bin Ibrahim bin Hashim, from his father, from Muhammed bin Abu ‘Umayr, from Hafs bin Bukhturi, from Abu Abdillah, peace be upon him, that he said: When the Messenger of Allah, Allah’s blessings be upon him and his Family, was ascended and the (time for) prayer arrived, Jibra’eel, peace be upon him, performed the Adhan. When he said: «Allah is Greater» the Angels said: Allah is Greater, Allah is Greater. When he said: «I testify that there is no god but Allah» the Angels said: The opponents have been negated. When he said: «I testify that Muhammed is the Messenger of Allah» the Angels said: A Prophet has been sent. When he said: «Hasten to prayer» the Angels said: He has motivated to worship of his Lord. When he said: «Hasten to success» the Angels said: Successful is the one who follows him.
