﴿ قَالَ فَإِنَّهَا مُحَرَّمَةٌ عَلَيْهِمْ ۛ أَرْبَعِينَ سَنَةًۭ ۛ يَتِيهُونَ فِى ٱلْأَرْضِ ۚ فَلَا تَأْسَ عَلَى ٱلْقَوْمِ ٱلْفَٰسِقِينَ ﴾

“Answered He: "Then, verily, this [land] shall be forbidden to them for forty years, while they wander on earth, bewildered, to and fro; and sorrow thou not over these iniquitous folk."”

((Their Lord) said) to Moses: (For this the land will surely be forbidden them) i.e. to enter it, after you called them wrong-doing folk (for forty years that they will wander in the earth, bewildered) they will be bewildered in the wilderness, confined in an area of seven parasangs, unable to get out of it or be guided to the right way. (So grieve not over) do not be saddened about (the wrong-doing folk).
