يَوْمَ يُحْمَىٰ عَلَيْهَا فِى نَارِ جَهَنَّمَ فَتُكْوَىٰ بِهَا جِبَاهُهُمْ وَجُنُوبُهُمْ وَظُهُورُهُمْ ۖ هَٰذَا مَا كَنَزْتُمْ لِأَنفُسِكُمْ فَذُوقُوا۟ مَا كُنتُمْ تَكْنِزُونَ
Important Words:
تکوی (branded) is formed from کوی. They say کواہ i.e. he cauterized him or it; he burnt his or its skin with a piece of iron or the like (Lane). کویت الدابة means, I cauterized or branded the beast with a piece of hot iron (Mufradat). کوت العقرب فلانا means, the scorpion stung such a one. الکی which is the noun-infinitive from کوی means, the act of cauterizing or branding with a piece of hot iron (whether for the purpose of putting a mark or for curing a disease). The Arabs say آخر الدواء الکی i.e. the last remedy (in certain diseases) is cauterizing (Aqrab).
Commentary:
The reward and punishment of the life to come will not be of a physical nature, but will be the spiritual representation of the actions of man in the present life. This is clear from the verse under comment, which states that only three parts of the body—the forehead, the side and the back—will be branded.
The expression is clearly figurative. When a rich man, out of miserliness or pride, refuses to help a beggar, the first sign that appears on his person is that his forehead contracts into a frown. Then he turns on his side, and finally he disdainfully shows his back to the man seeking his help. Fittingly, therefore, the forehead, the side and the back have been spoken of here as being branded, i.e. in the afterlife these parts will appear to be branded with a hot iron, as if bearing testimony against themselves.
The verse also signifies that even in the present life the hoarded treasures of Jews and Christians will become a source of grievous punishment for them. In this case, the threatened punishment might be taken to refer to devastating wars such as the present one, in which hot metal in various forms is destroying the western peoples. They receive it on their foreheads, sides and backs, i.e. whether facing the enemy or making a flank movement or turning their backs; and, curiously enough, Jews are as much hit by these wars as are Christians.
The expression seems to be figurative. When a rich man, out of miserliness or pride, refuses to help a needy person, his forehead becomes contracted into a frown. Then he turns aside and finally disdainfully shows his back to the man seeking his help. Quite appropriately, it is mentioned that the foreheads, the sides and the backs will be branded.
