ꜤAllāmah Fakhr al-Dīn Ḥarrālī رَحْمَةُ الـلّٰـهِ عَـلَيْه, has given another Madani pearl regarding this. He states: “The literal meaning of 'Ummī' is 'unschooled'. When the word 'Ummī' is used for an ordinary person, it means 'illiterate.' However, when it is used in reference to the Prophet صَلَّى الـلّٰـهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم, it does not mean (illiterate, but its meaning at that time) will be: يُقْرِئُهُ اللهُ مَا كَتَبَهُ بِيَدِهِ  . In other words, the one whom Allah Almighty taught the things that He had written with His Hand of Power from eternity, is called Ummī.^[1]

Everything Became Clear

The companion of the Prophet, Sayyidunā MuꜤādh b. Jabal رَضِىَ اللّٰهُ عَـنْهُ, narrates: Once, it was time for the Fajr prayer, and the Prophet صَلَّى الـلّٰـهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم arrived a little later than usual. He led the Fajr prayer and then said: 'Last night I woke up and offered voluntary prayers. During the prayer, I fell asleep and had a dream in which I saw my Lord in an exceedingly beautiful form. I saw that Allah Almighty placed His Hand of Power (as befits His Majesty) between my shoulders, to the extent that I felt its coolness on my chest. As soon as my Lord placed His Hand (as befits His Majesty) on my chest, my state became such that:

فَتَجَلّٰی لِيْ كُلُّ شَيْءٍ وَعَرَفْتُ

Everything became clear to me, and I came to know it.^[2]

In another narration, it is reported:

فَعَلِمْتُ مَا فِي السَّمَاوَاتِ وَمَا فِي الْأَرْضِ

Then I came to know everything that is in the heavens and the earth.^[3]

 !سُبْحٰنَ اللہThis is the glorious rank of the Prophet, صَلَّى الـلّٰـهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم being Ummī.
