What is the ruling on melodic composition and beautifying the voice in the adhan and during supplication?

The questioner:
He says: Honorable Shaykh, may Allah grant you success, what is the ruling on melodic composition and beautifying the voice in the adhan and during supplication?

The Shaykh:
In the case of the adhan, it is required. Improving the voice for it and raising the voice for the adhan is a good thing. But it is not melodic composition or beautifying the voice in that way; melodic composition is for songs. As for the adhan, it is the remembrance of Allah (Mighty and Majestic); one improves the voice for it and raises the voice for it, without exaggeration.

The presenter:
The rest of the question.

The questioner:
You say melodic composition and beautifying the voice in the adhan and during…

The Shaykh:
Yes, fine. Makkah now, no.

The presenter:
Yes. And during supplication.

The questioner:
Supplication is not that; it is more about reciting the Qur'an, and that is what is beautified in it.

The Shaykh:
Your voice. As for supplication, it is not the Qur'an. Yes, a loud voice. Yes.
