Wahafithnaha min kulli shaytanin rajeem (surah Hijr: 17)

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(15:17) and guarded them from every accursed Satan. *10 No Satan can pass through them

Wa hafiznaahaa min kulli Shaitaanir rajeem

*10) That is, "These spheres are so fortified that they are beyond the reach of every Satan, for all Satans including those of jinns, have been confined to that sphere in which the Earth has been placed and they enjoy no more access to visit other spheres than the other dwellers of this sphere. This has been mentioned in order to remove a common misunderstanding. The common people believed, .and still believe, that Satan and his descendants have a free access to every place in the universe. On the contrary, the Qur'an says that Satans cannot go beyond a certain limit and they have no unlimited power of ascension.
