وَٱذۡكُرُواْ نِعۡمَةَ ٱللَّهِ عَلَيۡكُمۡ وَمِيثَٰقَهُ ٱلَّذِي وَاثَقَكُم بِهِۦٓ إِذۡ قُلۡتُمۡ سَمِعۡنَا وَأَطَعۡنَاۖ وَٱتَّقُواْ ٱللَّهَۚ إِنَّ ٱللَّهَ عَلِيمُۢ بِذَاتِ ٱلصُّدُورِ٧

wa-udh'kurū niʿ'mata l-lahi ʿalaykum wamīthāqahu alladhī wāthaqakum bihi idh qul'tum samiʿ'nā wa-aṭaʿnā wa-ittaqū l-laha inna l-laha ʿalīmun bidhāti l-ṣudūri

And remember the favor of Allāh upon you and His covenant with which He bound you when you said, "We hear and we obey"; and fear Allāh. Indeed, Allāh is Knowing of that within the breasts.
