Some people say that the one who sings in his adhan is an innovator and that one should not repeat after him. Is this correct? And does the one who sings in his adhan drop the obligation?

The Shaykh : Some people say: The one who sings in his adhan is an innovator and one should not repeat after him. Is this correct, and does the one who sings in his adhan drop the obligation?
The scholars did not say that singing is forbidden; rather, they said that it is disliked. If it is disliked, then the act is that of the mu'adhdhin, but you should follow him, because this is a lawful adhan and the obligation is fulfilled by it. Do you understand?
Very well.
