Chapter on the Adhan (Call to Prayer) and the Iqamah

And from him, from Ali ibn Muhammad from Sahl from Ibn Mahbub from Abdullah ibn Sinan: Abu Abdillah عليه السلام said: “The height of the wall of Mosque of the Messenger of Allah سبحانه وتعالى, may Allah سبحانه وتعالى bless him and his family, was the height of a man, so He صلى الله عليه وعلى آله وسلم, peace be upon him, used to say to Bilal; ‘When the time (for prayer) enters, O Bilal, climb up on top of the wall and raise your voice with the Adhan, for indeed Allah سبحانه وتعالى, the Mighty and Majestic, has assigned a wind for the Adhan that carries it up to the heavens. And indeed, when the angels hear the Adhan from the people of the earth, they say: ‘These are the voices of the nation of Muhammad صلى الله عليه وعلى آله وسلم, may Allah سبحانه وتعالى bless him and his family, proclaiming the oneness of Allah سبحانه وتعالى, the Mighty and Majestic, and they seek forgiveness for the nation of Muhammad صلى الله عليه وعلى آله وسلم, may Allah سبحانه وتعالى bless him and his family, until they complete that prayer.’”
