Surah Al-Hujurat, ayah 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

Qālatil-a'rābu āmannā qul lam tu'minū walākin qūlū aslamnā walammā yadkhulil-īmānu fī qulūbikum wa in tutī'ullāha warasūlahū lā yalitkum min a'mālikum shay'an innallāha ghafūrur rahīm

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 Allāh and His Messenger, He will not deprive you from your deeds¹⁵²² of anything. Indeed, Allāh is Forgiving and Merciful."
