﴿ إِذْ يُغَشِّيكُمُ ٱلنُّعَاسَ أَمَنَةًۭ مِّنْهُ وَيُنَزِّلُ عَلَيْكُم مِّنَ ٱلسَّمَآءِ مَآءًۭ لِّيُطَهِّرَكُم بِهِۦ وَيُذْهِبَ عَنكُمْ رِجْزَ ٱلشَّيْطَٰنِ وَلِيَرْبِطَ عَلَىٰ قُلُوبِكُمْ وَيُثَبِّتَ بِهِ ٱلْأَقْدَامَ ﴾

“[Remember how it was] when He caused inner calm to enfold you, as an assurance from Him, and sent down upon you water from the skies, so that He might purify you thereby and free you from Satan's unclean whisperings and strengthen your hearts and thus make firm your steps.”

When He caused, the slumber of the calming of the corporeal faculties and the ego-centric attributes, to overcome you, by the sending down of the divine peace as security from God and as a reassurance; and sent down upon you, the, water, of the knowledge of certainty, from, the heaven of the spirit, to purify you thereby, from the wickedness of the whisperings of the soul and the murmurings of illusion, and to remove from you the evil, of the whisperings, of Satan, and his attempts to instill fear [in you], and to strengthen your hearts, that is, to fortify your hearts with the strength of certainty and to calm your agitation, and to make firm your feet, for valour and firmness of foot in the face of fear and mortal danger can only be through the strength of certainty.
