Tafsir of Yunus 10:6

"Indeed, in the alternation..."

He specified the God-fearing (al-muttaqin) because they are wary of the final outcome, and this wariness compels them to reflect and contemplate.

{Indeed, those who do not expect the meeting with Us and are satisfied with the life of this world and feel secure therein, and those who are heedless of Our signs—those will have their refuge in the Fire for what they used to earn.}
