﴿ وَلَا نُكَلِّفُ نَفْسًا إِلَّا وُسْعَهَا ۖ وَلَدَيْنَا كِتَٰبٌۭ يَنطِقُ بِٱلْحَقِّ ۚ وَهُمْ لَا يُظْلَمُونَ ﴾

“And [withal.] We do not burden any human being with more than he is well able to bear: for with Us is a record that speaks the truth [about what men do and can do]; and none shall be wronged.”

أُولَـٰئِكَ يُسَارِ‌عُونَ فِي الْخَيْرَ‌اتِ وَهُمْ لَهَا سَابِقُونَ Those people are accelerating towards the (real) good things, and they are the foremost to attain them. - 23:61 The meaning of مُسَارَعَت فِی الخَیرَات is that just as ordinary human beings run after worldly gains and try to leave other competitors behind, these good and virtuous people strive to gain spiritual reward and try to excel others in their efforts to fulfill their religious obligations.
