Who is a true Believer?

In the Name of Allah, the Most Gracious, the Most Merciful. [قَدْ أَفْلَحَ الْمُؤْمِنُونَ - الَّذِينَ هُمْ فِى صَلاَتِهِمْ خَـشِعُونَ - وَالَّذِينَ هُمْ عَنِ اللَّغْوِ مُّعْرِضُونَ - وَالَّذِينَ هُمْ لِلزَّكَـوةِ فَـعِلُونَ - وَالَّذِينَ هُمْ لِفُرُوجِهِمْ حَـفِظُونَ - إِلاَّ عَلَى أَزْوَجِهِمْ أَوْ مَا مَلَكَتْ أَيْمَـنُهُمْ فَإِنَّهُمْ غَيْرُ مَلُومِينَ - فَمَنِ ابْتَغَى وَرَآءَ ذلِكَ فَأُوْلَـئِكَ هُمُ الْعَادُونَ - وَالَّذِينَ هُمْ لاًّمَـنَـتِهِمْ وَعَهْدِهِمْ رَعُونَ ] وَالَّذِينَ هُمْ عَلَى صَلَوتِهِمْ يُحَـفِظُونَ- أُوْلَـئِكَ هُمُ الْورِثُونَ- الَّذِينَ يَرِثُونَ الْفِرْدَوْسَ هُمْ فِيهَا خَـلِدُونَ-] (1. Successful indeed are the believers.) (2. Those who with their Salah are Khashi`un.) (3. And those who turn away from Al-Laghw.) (4. And those who pay the Zakah.) (5. And those who guard their private parts.) (6. Except from their wives or their right hand possessions, for then, they are free from blame.) (7. But whoever seeks beyond that, then those are the transgressors.) (8. Those who are faithfully true to their Amanat and to their covenants are Ra`un.) (9. And those who strictly guard their Salawat.) (10. These are indeed the heirs. ) (11. Who shall inherit Firdaws. They shall dwell therein forever.)
