Is more than one adhan prescribed for Jumu'ah?

The Shaykh : Fourth and finally, in this paper, what is the prescribed number of adhans on Friday, and when is each adhan to be performed? It appears from the question that the questioner means: Is more than one adhan prescribed for Jumu'ah? The answer is that only one adhan is prescribed, and the time for this adhan is when the khatib ascends the minbar. It is established in Sahih al-Bukhari: "That the Prophet (peace and blessings be upon him), when he came out of his house, would ascend the minbar and sit. Then Bilal would stand up and call the adhan. When Bilal finished the adhan, the Messenger (peace and blessings be upon him) would stand up. When he finished the khutbah, he would call the iqamah for the prayer. And at that time, there was only one adhan." As for the second adhan, it was something instituted by 'Uthman ibn 'Affan (may Allah be pleased with him). However, this is not what they are doing today. There is a great difference between the 'Uthmanic adhan and the adhan that exists today. 'Uthman's adhan was at al-Zuraa, which is a place outside the Prophet's Mosque on the outskirts of Madinah, where people used to engage in buying and selling on Friday, meaning in the manner called today the Friday market. So the people would gather there on Friday, and the adhan of the mu'adhdhin at the Prophet's Mosque would not reach them. So 'Uthman established an adhan there to inform them of the arrival of the time for prayer. This means that if there had been a loudspeaker in the time of 'Uthman, he would have run a wire from the mu'adhdhin on the back of the mosque to the location of the market, and they would have heard the single adhan. But this means did not exist at that time, and so he was compelled to institute that adhan in that place to ensure the adhan was heard. But with the passage of time, this adhan changed and was brought into the Prophet's Mosque, and it is like this today, unfortunately, in the Prophet's Mosque. That is, the first adhan is as it is here today on the minaret, and the second adhan is in the mosque. This is a reversal of the Sunnah. On Friday, there is only one adhan, and this single adhan is when the khatib ascends the minbar. The adhan on the back of the mosque, not in the mosque, is the prescribed adhan, and nothing else.
