The prophet (saw) had four things to give to the companions to transform their lives from the ignorance to the enlightened life in the Surah Al-Jumu’ah [62:2] of the Quran.
The Quran itself is the biggest source of knowledge; it’s not enough just to know Arabic. You have to know what Allah meant by those Arabic words. So this is another whole section of knowledge, which the prophets (saw) passed onto the sahaba.
It’s not just enough to recite the Quran. We need to know what those specific meanings of the Quran are sent to us.
But if you don’t know when to apply that knowledge, where to apply that knowledge; You don’t know how much of the knowledge to apply. Then you basically hit another big rock.
When to apply that knowledge, where to apply that knowledge, how much of that knowledge to apply, to whom to apply that knowledge to these all hikmah, and purify heart by removing illnesses like arrogance, pride, jealousy in heart to function that knowledge well
So our attitude and so on inside needs to change to save ourselves from the days of ignorance, of the days of jahiliyyah by gaining the spiritual cleanliness.
So the prophet (saw) came to recite the verses, He came to teach us the book, the meaning of the book, he taught us how much to apply what not to apply from his Sunnah, to have his wisdom of knowing where to apply, to whom to apply to, and most importantly after that is for our own spiritual cleanliness of the heart, the prophet salallahu alaihe Salam also gave us that teaching that was supposed to clean our inside.
