وَمَا يَسۡتَوِى ٱلۡأَعۡمَىٰ وَٱلۡبَصِيرُ وَٱلَّذِينَ ءَامَنُواْ وَعَمِلُواْ ٱلصَّٰلِحَٰتِ وَلَا ٱلۡمُسِىٓءُ ۚ قَلِيلًا مَّا تَتَذَكَّرُونَ

وَمَا يَسۡتَوِى ٱلۡأَعۡمَىٰ وَٱلۡبَصِيرُ

You can look at the sky and fail to see its lesson, or you can see it and understand what it teaches about humility.

Nor are those who believe and do righteous deeds and the evildoer.
قَلِيلًا مَّا تَتَذَكَّرُونَ
Little do you remember.
How little effort you make to truly grasp and remember these truths.
