49:14
۞ قَالَتِ ٱلۡأَعۡرَابُ ءَامَنَّاۖ قُل لَّمۡ تُؤۡمِنُواْ وَلَٰكِن قُولُوٓاْ أَسۡلَمۡنَا وَلَمَّا يَدۡخُلِ ٱلۡإِيمَٰنُ فِي قُلُوبِكُمۡۖ وَإِن تُطِيعُواْ ٱللَّهَ وَرَسُولَهُۥ لَا يَلِتۡكُم مِّنۡ أَعۡمَٰلِكُمۡ شَيۡـًٔاۚ إِنَّ ٱللَّهَ غَفُورٞ رَّحِيمٌ ١٤

The bedouins say, "We have believed." Say, "You have not [yet] believed; but say [instead], 'We have submitted,' for faith has not yet entered your hearts. And if you obey Allah and His Messenger, He will not deprive you from your deeds of anything. Indeed, Allah is Forgiving and Merciful."
