All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.
There is no doubt that a Muslim during the prayer is talking to his Lord as per the Hadeeth reported by Al-Bukhari and Muslim and narrated by Anas that the Prophet said: ''If he [i.e. a Muslim] is in the prayer, then he is talking to his Lord…” However, the prayer is not the only act by which a servant can talk to his Lord. There is a talk in supplication, in the mention of Allaah and in the recitation of the Quran. The prayer includes all of these.
Allaah Knows best.
