When the Prophet recovered back to normal state...
When the Prophet recovered back to normal state, he asked Ali, ‘Did you hear that?’ ‘Yes!’ he replied. ‘Did you memorize it?’ the Prophet asked again. Ali answered, ‘Yes!’ The Prophet stated, ‘Call Bilal and teach him the Adhan .’ Ali called Bilal and taught him the Adhan . ^4 These two traditions include two times of calling out the Adhan by Gabriel, once for the Prophet in his Ascension to heaven and the other for the religious declaration of it.
Attention must be paid to the fact that the frequency of a revelation, even if it is twice, is quite important. The viewpoint of the Sunnis Sunnis in general have two viewpoints about the outset of the Adhan in religion, regardless of its features; the origin of Adhan is (1) a revelation or (2) a dream. In his book entitled Al-Mabsut , Sarakhsi says: Abu Hafs Muhammad Ibn Ali denied that the origin of Adhan is a dream.
He said, “You are attacking one of the religion’s clearest signs saying that it is proved by a dream. Never! Rather, when the Prophet (a.s) was taken to Masjid Al-Aqsa and was surrounded by the other Prophets, an angel called out the Adhan and iqamah and the Prophet (a.s) prayed along with them.
It is said that Gabriel (a.s) descended with the Adhan .”[^5] In Umda Al-Qari fi Sharh Sahih Al-Bukhari , it is recorded that Zamakhshari has quoted some people that the Adhan was descended by a Divine Revelation, not a dream.[^6] In Al-Bahr Al-Ra’iq , we read, “The origin of Adhan is Gabriel’s Adhan and iqamah in the night of the Prophet’s Ascension to the heaven, when the Prophet (a.s) led the prayer of the angels and the Prophets’ souls.
