Doa before and after adhaan and iqomah

I would like to know what say(doa) before adhaan and iqomah and after adhaan and iqomah.

Praise be to Allaah.

1 – With regard to du’aa’ before the adhaan, there is no du’aa’ to be recited before the adhaan as far as I know. If that time is singled out for any type of du’aa’, this is a reprehensible innovation (bid’ah). But if it is done by coincidence and accidentally then there is nothing wrong with it.

2 – With regard to before the iqaamah, when the muezzin is about to start the iqaamah, we know of no specific words to be recited at this time. Doing so when there is no solid shar’i evidence is a reprehensible innovation (bid’ah).

3 – With regard to the time between the adhaan and iqaamah, du’aa’ is encouraged at this time and it is mustahabb.
