It is recommended, before starting any obligatory prayer, to make two (2) calls. The first is called adhan. It is meant to invite the Muslims to preform the prayer. It is done loudly and slowly. After the adhan, another call, iqamah, is made. It is made to alert the Muslims that the prayer is about to start. These two calls are recommended whether the prayer is performed individually or in congregation (see Notes).
It is recommended for the mu’adhdhin (person calling adhan) to have wudu‘ face the Qiblah, say the statements softly to oneself before saying them out loud. For the listener, it is recommended to repeat (softly) exactly after the mu’adhdhin, except in # 5 & 6 where la hawla wa la quwwata illa billah لا حول ولا قوة إلا بالله is said instead. After adhan, it is recommended to say as-Salah ^alan-Nabiyy, such as اللهم صل على محمد وسلم It is also recommended to have wudu‘ for calling iqamah, face the Qiblah, and say it in a faster manner than saying the adhan.
