الآية رقم (26) - قَالَ فَإِنَّهَا مُحَرَّمَةٌ عَلَيْهِمْ أَرْبَعِينَ سَنَةً يَتِيهُونَ فِي الأَرْضِ فَلاَ تَأْسَ عَلَى الْقَوْمِ الْفَاسِقِينَ
(26) - ([Allah] said, "Then indeed, it is forbidden to them for forty years [in which] they will wander throughout the land. So do not grieve over the defiantly disobedient people.")
This is an evidence that it is forbidden to them forever, the scholars said: It is forbidden to them permanently and not only for forty years because they did not walk on the path of guidance, although they were with Moses and Aaron (PBUT), who died in the distraction land.
