وَاذكُروا نِعمَةَ اللَّهِ عَلَيكُم وَميثاقَهُ الَّذي واثَقَكُم بِهِ إِذ قُلتُم سَمِعنا وَأَطَعنا ۖ وَاتَّقُوا اللَّهَ ۚ إِنَّ اللَّهَ عَليمٌ بِذاتِ الصُّدورِ

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