الانفال — Al-Anfal Ayat 11
اِذْ يُغَشِّيْكُمُ النُّعَاسَ اَمَنَةً مِّنْهُ وَيُنَزِّلُ عَلَيْكُمْ مِّنَ السَّمَاۤءِ مَاۤءً لِّيُطَهِّرَكُمْ بِهٖ وَيُذْهِبَ عَنْكُمْ رِجْزَ الشَّيْطٰنِ وَلِيَرْبِطَ عَلٰى قُلُوْبِكُمْ وَيُثَبِّتَ بِهِ الْاَقْدَامَۗ
Iż yugasysyīkumun-nu‘āsa amanatam minhu wa yunazzilu ‘alaikum minas-samā'i mā'al liyuṭahhirakum bihī wa yużhiba ‘ankum rijzasy-syaiṭāni wa liyarbiṭa ‘alā qulūbikum wa yuṡabbita bihil-aqdām(a).
"[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."
