Dr. Mustafa Khattab, the Clear Quran - Surah Al-Anfal, ayah 11

Translation of Surah Al-Anfal, ayah 11 (8:11)

إِذۡ يُغَشِّيكُمُ ٱلنُّعَاسَ أَمَنَةٗ مِّنۡهُ وَيُنَزِّلُ عَلَيۡكُم مِّنَ ٱلسَّمَآءِ مَآءٗ لِّيُطَهِّرَكُم بِهِۦ وَيُذۡهِبَ عَنكُمۡ رِجۡزَ ٱلشَّيۡطَٰنِ وَلِيَرۡبِطَ عَلَىٰ قُلُوبِكُمۡ وَيُثَبِّتَ بِهِ ٱلۡأَقۡدَامَ ١١
˹Remember˺ when He caused drowsiness to overcome you, giving you serenity.1 And He sent down rain from the sky to purify you, free you from Satan’s whispers, strengthen your hearts, and make ˹your˺ steps firm.
