Surah Al-Hujurat · 14
۞ قالَتِ الأَعرابُ ءامَنّا ۖ قُل لَم تُؤمِنوا وَلٰكِن قولوا أَسلَمنا وَلَمّا يَدخُلِ الإيمٰنُ فى قُلوبِكُم ۖ وَإِن تُطيعُوا اللَّهَ وَرَسولَهُ لا يَلِتكُم مِن أَعمٰلِكُم شَيـًٔا ۚ إِنَّ اللَّهَ غَفورٌ رَحيمٌ
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
