The Trustworthy Angel brought Allah's Revelation to the Trustworthy Messenger

Allah the Exalted states that the Message His servant and Messenger Muhammad ﷺ brought to people was taught to him by,

شَدِيدُ الْقُوَى

عَلَّمَهُ شَدِيدُ الْقُوَىٰ (It is taught to him by one [ angel ] of strong faculties,...53:5) From here upto the eighteenth verse, لَقَدْ رَ‌أَىٰ مِنْ آيَاتِ رَ‌بِّهِ الْكُبْرَ‌ىٰ the subject-matter is the revelation from Allah. It has been established that the Qur'an is a record of verbal revelation vouchsafed to the Holy Prophet Muhammad ﷺ . There is no room for doubt about the fact that it is the very Words of Allah. It was sent down in such a way that no possibility of confusion or error ever existed.
