إِذْ يُغَشِّيكُمُ ٱلنُّعَاسَ أَمَنَةًۭ مِّنْهُ وَيُنَزِّلُ عَلَيْكُم مِّنَ ٱلسَّمَآءِ مَآءًۭ لِّيُطَهِّرَكُم بِهِۦ وَيُذْهِبَ عَنكُمْ رِجْزَ ٱلشَّيْطَٰنِ وَلِيَرْبِطَ عَلَىٰ قُلُوبِكُمْ وَيُثَبِّتَ بِهِ ٱلْأَقْدَامَ
[Remember] when He overwhelmed you with drowsiness [giving] security from Him and sent down upon you from the sky, rain by which to purify you and remove from you the evil [suggestions] of Satan and to make steadfast your hearts and plant firmly thereby your feet.
Remember, when He caused slumber to overcome you as security, against the fear that had befallen you, from Him, from God, and sent down upon you water from the heaven, to purify you thereby, from minor and major ritual impurities; and to remove from you the evil of Satan, his whisperings to you that, had you been on the right path, you would not have been thirsty and impure, while the idolaters enjoyed [access to] water; and to strengthen, to seal, your hearts, with certainty and endurance; and to make firm your feet, lest they sink in the sand.
