Is it permissible for the muezzin to record the correct Adhan to use as a reference, or to save a link to an audio recording of a correct Adhan, and is it sufficient to listen to the Adhan recited in Mecca or Medina for this purpose?

The Prophet Muhammad (peace be upon him) encouraged inviting people to Allah and teaching what is good. Whoever calls to guidance will have a reward like that of those who follow him, and whoever calls to misguidance will bear a sin like that of those who follow him. The hadith indicates that "Allah and His angels and the inhabitants of the heavens and the earth, even the ant in its hole and even the whale, send blessings upon the one who teaches people good." Recording the Adhan in accordance with Islamic law, with the intention of spreading the Sunnah and teaching the ignorant, falls within inviting people to Allah. Therefore, there is no objection to recording it and uploading it to websites for educational purposes. However, it must be noted that a recorded Adhan is not sufficient for announcing the entry of prayer time in mosques, and it is wrong to dispense with the muezzin's Adhan by using a recording.
