The ruling on the imam reading from the mushaf in the obligatory prayer

Question:
He says: Honorable Shaykh, may Allah grant you success. We have an imam who has taken a leave of absence for a few days, and the mu'adhdhin has taken over. The mu'adhdhin leads the congregation in the Fajr prayer, but he opens the mushaf during the prayer, the obligatory prayer. Is there any harm in that?

Answer:
Have things reached this point? One of the brothers who has memorized the Qur'an, or has memorized parts of the Qur'an, should take his place instead of the mu'adhdhin who does not read except from the mushaf. Have things reached this point? Yes.
