So many people in the whole world that have memorized al Quran. Children, teenagers, mid-ages, adults, even the old people have proved that al Quran is memorable.
Allah ﷻ said:
وَلَقَدْ يَسَّرْنَا الْقُرْآنَ لِلذِّكْرِ فَهَلْ مِن مُّدَّكِرٍ
“And We have certainly made the Qur’an easy for remembrance, so is there any who will remember?” [An-Najm:17].
Allah ﷻ also said:
إِنَّا جَعَلْنَاهُ قُرْآنًا عَرَبِيًّا لَعَلَّكُمْ تَعْقِلُونَ
“Indeed, We have made it an Arabic Qur’an that you might understand.” (Az Zukhruf: 3).
Word “easy” in this verse means: easy to be memorized [Tafheemul Quran].
So, let’s try to memorize al Quran, and don’t forget also to implement what’s inside it.
