The desert Arabs say, "We believe." Say, "Ye have no faith; but ye (only)say, 'We have submitted our wills to God,' For not yet has Faith entered your hearts. But if ye obey God and His Apostle, He will not belittle aught of your deeds: for God is Oft-Forgiving, Most Merciful." (49:14)

Only those are Believers who have believed in God and His Apostle, and have never since doubted, but have striven with their belongings and their persons in the Cause of God: Such are the sincere ones, Were We then weary with the first Creation, that they should be in confused doubt about a new Creation? (49:15)
