Is It Permissible To Make Dua Of Adhan Loudly In Mosques?

Is it permissible to make dua of adhan loudly in mosques?

What is important in acts of worship and dhikrs is that they are tawqifi. That is to say, they are practised as they are defined in the Qur’an and Sunnah. It is a sunnah of the dua of adhan to make it without raising the voice. However, sometimes it is recited loudly in mosques so that people learn it. It is permissible to make duas, which were narrated from the Prophet Muhammad (saw), loudly like this, for teaching it to other people. However, it is not permissible to recite it loudly after people learn it (al-Fatawa al-Hindiyyah, V, 393).
