إِذ يُغَشّيكُمُ النُّعاسَ أَمَنَةً مِنهُ وَيُنَزِّلُ عَلَيكُم مِنَ السَّماءِ ماءً لِيُطَهِّرَكُم بِهِ وَيُذهِبَ عَنكُم رِجزَ الشَّيطانِ وَلِيَربِطَ عَلىٰ قُلوبِكُم وَيُثَبِّتَ بِهِ الأَقدامَ

[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.
