11إِذ يُغَشّيكُمُ النُّعاسَ أَمَنَةً مِنهُ وَيُنَزِّلُ عَلَيكُم مِنَ السَّماءِ ماءً لِيُطَهِّرَكُم بِهِ وَيُذهِبَ عَنكُم رِجزَ الشَّيطانِ وَلِيَربِطَ عَلىٰ قُلوبِكُم وَيُثَبِّتَ بِهِ الأَقدامَLaleh BakhtiarMention when a sleepiness enwraps you as a safety from Him. He sends down water from heaven for you and He purifies you by it and causes to be put away from you the defilement of Satan. He invigorates your hearts and makes your feet firm by it.
