3a] Was the adhaan revealed by wahy or was it suggested by a sahaabi?

3a]
You may ask, why did the adhaan start in this fashion, being seen in a dream by two sahaabis then being confirmed by the wahy? Why was it notrevealed directly? The answer is that Allaah decrees whatever He wills, however He wills, may He be glorified and exalted. Perhaps the way it happened was meant todemonstrate the virtue of these two sahaabis and toconfirm the how good this ummah is, because among them are some whose opinions coincide with the wahy and some who had true dreams which confirmed their truthfulness, for the people who have the truest dreams are the truest in speech as the Prophet (peace and blessings of Allaah be upon him) said.
Finally:
The definition of the Sunnah given in the books of the scholars is that it consists of everything that was narrated from the Messenger (peace and blessings of Allaah be upon him), everything that he “said, did or approved of.”
What is meant by his words and actions is clear.What he approved of refers to when someone did something in front of him and he approved of it– this is also part of the sharee’ah, not because that person did it, but because the Messenger (peace and blessings of Allaah be upon him) approved of it. The Messenger (peace and blessings of Allaah be upon him) never kept quiet about falsehood andhe never approved of anything false or misguided that was done by others. He would disapprove of it and speakout against it, as he did in the case of the sahaabi Abu Israa’eel, as was narrated by Ibn ‘Abbaas, who said: “Whilst the Prophet (peace and blessings of Allaah be upon him) was giving a khutbah, he saw a man standing in the sun, and he asked about him. They said, ‘That is Abu Israa’eel.He vowed to stand and not sit down, not to seek shade, not to speak, and to fast.’ He said, ‘Tell him to speak, seek shade and sit down, but let him complete his fast.’” (Narrated by al-Bukhaari, 6326).
The Prophet (peace and blessings of Allaah be upon him) approved of Abu Israa’eel’s vow to fast, but he cancelled the rest of his vow and did not approve of it.
So it is clear that the adhaan became part of the religion when the Prophet (peace and blessings of Allaah be upon him) confirmed what Allaah had shown the two sahaabis in their dreams, and commanded ‘Abd-Allaah ibn Zayd to teach it to Bilaal so that he could call the people toprayer. Hopefully the explanation given above will dispel your confusion and make matters clearer to you. We ask Allaah to grant us and you understanding of Islam. And Allaah knows best./ - - - :-> Transtors: 1.http://free-translation.imtranslator.net/lowres.asp 2.http://translate.google.com/m?twu=1&hl=en&vi=m&sl=auto&tl=en
