Surah Al-Anfal (The Spoils of War), Verse 11

اِذْ یُغَشِّیْكُمُ النُّعَاسَ اَمَنَةً مِّنْهُ وَیُنَزِّلُ عَلَیْكُمْ مِّنَ السَّمَآءِ مَآءً لِّیُطَهِّرَكُمْ بِهٖ وَیُذْهِبَ عَنْكُمْ رِجْزَ الشَّیْطٰنِ وَلِیَرْبِطَ عَلٰی قُلُوْبِكُمْ وَیُثَبِّتَ بِهِ الْاَقْدَامَ ۟

Iz yughashsheekumun nu'assa amanatam minhu wa yunazzilu 'alaikum minas samaaa'i maaa'al liyutah hirakum bihee wa yuzhiba 'ankum rijzash Shaitaani wa liyarbita 'ala quloobikum wa yusabbita bihil aqdaam

“Remember He covered you with a sort of drowsiness, to give you calm as from Himself, and he caused rain to descend on you from heaven, to clean you therewith, to remove from you the stain of Satan, to strengthen your hearts, and to plant your feet firmly therewith.”
