The First Adhan for Jumu'ah and the First Adhan for Fajr

Question:
Some people, O Shaykh, say that the first adhan for Jumu'ah did not exist in the time of the Messenger of Allah (peace and blessings be upon him), and it seems they do not see the permissibility of it?

Answer:
The Friday adhan is well known; it was not present in the early period of the Prophet (peace and blessings be upon him), but rather in the time of 'Uthman. As for the first adhan for the Fajr prayer, that is well known from the time of the Prophet (peace and blessings be upon him). However, was it established with the Fajr adhan from the very beginning, or was it legislated later? The point is that it is established and settled that Bilal would call the adhan at night, and the one who was appointed would call the adhan after the dawn appears. This is the sunnah (recommended practice): that there be a first adhan before the dawn to alert the people, so that the one who wants to pray witr or prepare for Fajr has ample time. As for Friday, it has two adhans: the adhan when the imam enters to deliver the khutbah, which is the established practice in the time of the Prophet (peace and blessings be upon him), and the second adhan, which is new and was introduced by 'Uthman, the righteous caliph. The Prophet (peace be upon him) said: "Act upon what I have left for you and ." So the Muslims acted upon it, calling the adhan a little before Friday to alert the people to the day of Friday. Yes.
