The Virtue of the Adhan and the Mu'adhdhins

Question:
Abu Muhammad says in this question: I hope that the Honorable Shaykh, may Allah protect you, will tell us about the virtue and reward of the adhan and the mu'adhdhins. May Allah reward you with good. In the name of Allah, the Most Gracious, the Most Merciful. Praise be to Allah, Lord of the worlds. May Allah send prayers and peace upon our Prophet Muhammad, and upon his family and all his Companions. As for what follows:

Answer:
There is no doubt that the virtue of the adhan is great. Because it is a call to good. A call to the prayer, which is the perfection of the pillars of Islam.
And Allah the Exalted and Majestic said: Some of the exegetes said that this verse was revealed regarding the mu'adhdhins. And there is no doubt that the verse includes them, that they call to Allah (Glorified and Exalted is He) and say: "Hasten to the prayer, hasten to success." And the Prophet (peace and blessings be upon him) said: the mu'adhdhins. And it was reported that nothing hears the mu'adhdhin except that it testifies for him on the Day of Resurrection, from the regions of the earth, and so on. This contains great virtue and great honor, the adhan.
There is no doubt that it is. A noble deed and a good deed. For the one whose intention is sound. And who seeks thereby the Face of Allah (Glorified and Exalted is He). Yes.
