Quran 8:11 from Surah Al-Anfaal on Divine Marvels.
إِذۡ يُغَشِّيكُمُ ٱلنُّعَاسَ أَمَنَةٗ مِّنۡهُ وَيُنَزِّلُ عَلَيۡكُم مِّنَ ٱلسَّمَآءِ مَآءٗ لِّيُطَهِّرَكُم بِهِۦ وَيُذۡهِبَ عَنكُمۡ رِجۡزَ ٱلشَّيۡطَٰنِ وَلِيَرۡبِطَ عَلَىٰ قُلُوبِكُمۡ وَيُثَبِّتَ بِهِ ٱلۡأَقۡدَامَ
English translation: When He covered you with [the] slumber a security from Him and sent down upon you from the sky water so that He may purify you with it and take away from you evil (suggestions) (of) the Shaitaan And to strengthen [on] your hearts and make firm with it your feet
Transliteration: idh yughashikumu al-nu'asa amanatan min'hu wayunazzilu alaykum mina al-samai maan liyutahhirakum bihi wayudh'hiba ankum rij'za al-shaytani waliyarbita ala qulubikum wayuthabbita bihi al-aqdama
