Al-Ma'idah' - 5:7

وَاذْكُرُواْ نِعْمَةَ اللّهِ عَلَيْكُمْ وَمِيثَاقَهُ الَّذِي وَاثَقَكُم بِهِ إِذْ قُلْتُمْ سَمِعْنَا وَأَطَعْنَا وَاتَّقُواْ اللّهَ إِنَّ اللّهَ عَلِيمٌ بِذَاتِ الصُّدُورِ
[5:7]
And remember the favor of Allah on you and His covenant with which He bound you firmly, when you said: We have heard and we obey, and be careful of (your duty to) Allah, surely Allah knows what is in the breasts.
And call in remembrance the favour of Allah unto you, and His covenant, which He ratified with you, when ye said: "We hear and we obey": And fear Allah, for Allah knoweth well the secrets of your hearts.
Remember Allah's grace upon you and His covenant by which He bound you when ye said: We hear and we obey; And keep your duty to Allah. Lo! He knoweth what is in the breasts (of men).
