Bukhari

Hadith Commentary:
In this entire hadith, the mention is of the descent of the first revelation (wahy).
Allah Ta’ala said:
He taught man by the pen.
If Allah Ta’ala had not inspired man with the method of the pen and writing, then man’s intellectual abilities would have remained extremely limited and confined.
This is the general practice of Allah Ta’ala, but the knowledge of the noble Prophets (alayhim as-salam) is not dependent on this pen.
Similarly, when a human being comes out from the mother’s womb, at that time he is also without knowledge; then Allah Ta’ala, even before the use of the pen, teaches him many things.

Hadith Commentary:
➊
Among the prophets of Bani Israel, Musa (alayhis salam) is a very eminent prophet.
His virtuous mention has appeared in numerous verses.
His birth and his entire subsequent life were among the great signs of Allah’s power.
He confronted the tyrannical ruler of his time, who used to call himself the “Supreme Lord” (the greatest lord).
Without a heavenly book, and relying only on hidden revelation (wahy khafi), that is, the blessed hadiths, he confronted him.
In the end, that ruler was wiped from the face of existence and became a lesson for those who came after.
This achievement of Musa (alayhis salam) is one that will be remembered as long as the world remains.

➋
In this hadith, a statement of Waraqah bin Nawfal is the point of reference:
“This is the confidant (keeper of secrets) whom Allah, the Exalted, sent down to Musa (alayhis salam).”
By this is meant the angel of revelation, Jibril (alayhis salam).

➌
After drowning Pharaoh, Allah, the Exalted, granted Musa (alayhis salam) a sacred book like the Torah, which was entirely guidance and light.
