According to the Holy Quran, human personality (self) has three possibilities:
1. Decay and disintegration: this is termed as ‘fujoor‘.
فَأَلْهَمَهَا فُجُورَهَا وَتَقْوَاهَا
Al-Quran Surah 91: Verse 8
2. Integration and preservation: this is termed as ‘taqwa‘.
3. Growth and development: this is termed as ‘tazkiya‘.
قَدْ أَفْلَحَ مَنْ زَكَّاهَا
Al-Quran Surah 91: Verse 9
The aim of life is to avoid decay and disintegration, and strive for integration, preservation, growth and development of the ‘self’.
