68وَمَن نُعَمِّرهُ نُنَكِّسهُ فِي الخَلقِ ۖ أَفَلا يَعقِلونَMuhammad AsadBut [let them always remember that] if We lengthen a human being's days, We also cause him to decline in his powers [when he grows old]: will they not, then, use their reason?1I.e., man should never postpone his exercise of moral choice - for if human beings are their devotees, even though to them they may superior creatures inasmuch as they have been endowed with the faculty of discernment and a wide measure of free will, let them also remember that "man has been created weak" (4:28) and liable to decline still further in old age, so that the time at his disposal is short.
