A moazzin ( مؤذن ) calls using the minaret loudspeakers of the mosques to announce every prayer. When it is the time of the prayer, you may be suprised by several Adhan Calls in the same time in your entourage coming from different mosques with a lag of a few seconds between them.
The words you will hear in the call of prayer in Morocco or in any muslim country is as follows:
1/ Allahu Akbar ! (repeated four times).
Meaning : God is Great
2/ Ashhadu an la ilaha illa Allah (repeated two times).
Meaning : I bear witness that there is no god except the One God.
Ashhadu anna Muhammadan Rasool Allah (repeated two times).
Meaning : I bear witness that Muhammad is the messenger of God.
3/ Hayya ala Salat (repeated two times).
Meaning : Hurry to the prayer (Rise up for Prayer).
4/ Hayya ala L Falah (repeated two times).
Meaning : Hurry to success (Rise up for Salvation).
5/ Allahu Akbar (repeated two times).
Meaning : God is Great!
6/ La ilaha illa Allah (One time)
Meaning : There is no god except the One God.
For the pre-dawn prayer called Fajr, the following phrase is inserted between the fourth and fifth part above (between Hayya ala L Falah and Allahu Akbar), towards the end :
As salatu Khayrun Mina nawm (repeated two times).
Meaning : Prayer is better than sleep.
