All of the Salat al Fatihi speaks on the reality of the Prophet Muhammad (SAW). From his creation and the manifestation of his reality from beginning to end. If one wants to study the reality of the Prophet from the beginning to end all one has to do is study the portents of Salat al Fatihi.
 
For the Prophet was and is the beginning of all creations and the key to the hidden realities (al Fatihi lima Ugliq) the opener of what was closed. And his love and acknowledgement and honor is the key to the lifting of the curtains and veils between the spiritual seeker and the divine presence.
 
He is also the Seal of what went before... meaning he was the Seal of Prophethood and also means any goodness, and maqam, any love of Allah, and level of knowledge, and any level of beauty, and any level of worship, and any level of yearning, and any level of taqwa, and any level of holiness WAS SEALED BY HIM.... meaning that NO OTHER will EVER reach was he has reaced in the levels of the aforementioned. HE IS THE SEAL OF WHAT WENT BEFORE. (he has reached what all others will never reach)
 
He is also the Nasri Haqq bil Haqq... meaning the Helper of the Truth with the Truth. Nasri Haqq is the one in which we receive ALL of our Support from Allah. whether this support is materially or spiritually. All what we receive from Allah comes through the mediation of His Reality. as we read in the hadith the Prophet said. "Allah is the One who gives, and I am the one who distributes what he gives".
And what the Prophet has supported ALL OF the Creation with(Arsh, Kursi, Heaven, Heal, Sirat, the Angels, the Prophets, the Messengers, the Awliya Allah, the Muslims, the Dunia, all other things of creation known and unknown) he has supported these with the HAQQ of ALLAH.
 
So the beloved Prophet is the SUPPORTER of the HAQQ, and if you ask how or with what he supports. The answer is WITH THE HAQQ of Allah. He is the Guide toward the Realm of God (Hadii Ila Ciratikal Mustakim).
