Ṭāhā

وَأَنَا اخْتَرْتُكَ فَاسْتَمِعْ لِمَا يُوحَي

إِنَّنِي أَنَا اللَّهُ لآ إِلَهَ إِلآَّ أَنَاْ فَاعْبُدْنِي وَأَقِمِ الصَّلاَةَ لِذِكْرِي

13. “And I myself have chosen you; therefore hearken unto what is revealed.”
14. “Verily I, I(alone), am Allah. There is no god save Me. So worship (only) Me, and establish prayer for My remembrance.”

Divine prophets have been appointed to prophethood by Allah, not by people. Therefore, the words of revelation, sent to them, should be heard and followed with whole the entity and heartily. In this holy verse, Allah says that He Himself has chosen him to Messengership, then he should hear His word and be steadfast on it. This is the Divine revelation that he was commanded to hear. The verse says:

Regarding Unity and sincere religion, Allah commanded him in this verse as follows:

In this verse Allah enjoins him to worship Him and to associate none in worshipping unto Him and to establish prayer in order that in His remembrance he glorifies and praises Him since prayer exists not save for the remembrance of Allah. Or the purpose of the content meaning in this holy verse is that he should establish prayer so that He (s.w.t.) also remembers him in praising. In other words, in this holy verse, next to the statement of the most importart principle of the prophets’ invitation, which is Unity, the subject of worshipping the One God, as a fruit for the tree of Faith and Unity, has been referred to.

And, immediately after it, He has enjoined prayer; i.e., the greatest worship and the most important link between the servants and the Creator, as well as the most effective means for that His Pure Essence might not be forgotten.
