11إِذ يُغَشّيكُمُ النُّعاسَ أَمَنَةً مِنهُ وَيُنَزِّلُ عَلَيكُم مِنَ السَّماءِ ماءً لِيُطَهِّرَكُم بِهِ وَيُذهِبَ عَنكُم رِجزَ الشَّيطانِ وَلِيَربِطَ عَلىٰ قُلوبِكُم وَيُثَبِّتَ بِهِ الأَقدامَN. J. DawoodYou were overcome by sleep, a token of His protection. He sent down water from the sky to cleanse you and to purify you of Satan’s filth, to strengthen your hearts and to steady your footsteps.
