The Messenger of Allah ﷺ said, “When Allah wishes good for someone, He bestows upon him the understanding of Deen.”
صحيح البخاري و مسلم
Understanding doesn’t mean only being able to read or hear the verses-it means being able to internalize and applying the teachings of Quran and sunnah.
It’s easy to quote and re-quote but hard to become a living example of knowledge with a good character.
The understanding of Quran isn’t going to come to you overnight, you’ll have to struggle and strive and work really hard to gain it.
Ultimately, if Allah wishes khair for a person, He guides his heart to seeking knowledge and spending time in the circles of knowledge where he can benefit from others and pass it onto others in the future.
