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

3]
I think i once read that the adhan (call to prayer)was suggested to our prophet Muhammed ( ) by another muslim after he said he didnt want to use the bells that the christians used or the rams-head(?) that the jews used to call people to prayer. How does the idea of everything the prophet ordered being an inspiration that is inspiredfit in with this?
I am not trying to be picky here, but am asking purely to aid my understanding.
Praise be to Allaah.
“Adhaan” in Arabic means conveying; in Islam it means announcing that the time (for prayer) has come. It was prescribed during the time of the Messenger of Allaah (peace and blessings of Allaah be upon him) in Madeenah. According to the hadeeth of ‘Abd-Allaah ibn Zayd ibn Abd Rabbihi, when the Messenger of Allaah (peace and blessings of Allaah be upon him) decided to use a bell eventhough he disliked it because it was like what the Christians used, ‘there appeared to me in a dream a man who was wearing two green garments, in whose hand was a bell. I said, “O slave of Allaah, will you sell thatbell?” he said, “What will you do with it?” I said, “We will call the people toprayer with it.” He said, “Shall I not show you something better than that?” I said, “Yes.” He said, “Say, Allaahu akbar Allaah akbar … (to the endof the adhaan).” When morning came, I went to the Messenger of Allaah (peace and blessings of Allaah be upon him) and told him what I had seen. He said, “This is a true dream, in sha Allaah. Get up with Bilaal and tell himwhat you have seen, so that he can give the call, because he has a more beautiful voice than you.” So I got up with Bilaal andstarted telling him what I had seen, and he gave thecall to prayer. ‘Umar ibn al-Khattaab heard that whilst he was in his house, and he came out, dragging his cloak behind him, saying, “By the One Who sent you with the truth, O Messenger of Allaah, I saw the same as he saw.” The Messenger ofAllaah (peace and blessings of Allaah be upon him) said: “To Allaahbe praise.”’ (Narrated by Ahmad, 1588; al-Tirmidhi,174; Abu Dawood, 421, 430; Ibn Maajah, 698).
It is clear from this hadeeth:
That the words of the adhaan came in a dream which was seen by a great sahaabi and approved of by our great Prophet. They were not a suggestion as you mentioned, but a dream, and it is known that dreams are one of the seventy parts of Prophethood, because it was stated in a hadeeth narrated by Ibn ‘Umar that the Prophet (peace and blessings of Allaah be upon him) said: “Dreams are one of the seventy parts of Prophethood.” (Narrated by Ahmad, 4449).
Al-Bukhaari narrated a different version: “True dreams are one of the forty-six parts of Prophethood.” (Narrated by al-Bukhaari,, 6474; Muslim, 4203, 42005).
The dream here, which the Prophet (peace and blessings of Allaah be upon him) described as a true dream, came from Allaah and was not a suggestion from a person.So it was a part of Prophethood because it was approved of by the Prophet (peace and blessings of Allaah be upon him) and was described by him as a truedream. If the Prophet had not approved of it, it would not have been considered a true dream and it would not have been a part of Prophethood. The one who judged it to be true was the Prophet (peace and blessings of Allaah be upon him), and the one who commanded them toact upon it was the Prophet (peace and blessings of Allaah be upon him), who received revelation (wahy) from his Lord.
‘Umar (may Allaah be pleased with him) had seen a similar dream. Let us not forget that ‘Umar was one of the Rightly-guided khaleefahs (al-khulafaa’ al-raashidoon), of whom the Messenger (peace and blessings of Allaah be upon him) said, “I exhort you to adhere to my sunnah (way) and the sunnah of the rightly-guided khaleefahs. Hold on tight to it with your back teeth.” (Narrated by al-Tirmidhi, 2600; Ibn Maajah, 43; Ahmad, 16519).
‘Umar’s view frequently coincided with the wahy and divine legislation. ‘Aa’ishah reported that the Prophet (peace and blessings of Allaah be upon him) used to say, “Among the nations who came before you there were people who were muhaddathoon (inspired).If there is anyone like this in my ummah, it is ‘Umar ibn al-Khattaab.” (Narrated by al-Bukhaari, 3282; Muslim, 2398). Ibn Wahb said muhaddathoon means inspired./ - - - :-> 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
