Sheikh Tabarsi has commented that there are three meanings for the self...

An example of the use of self to imply spirit is found in the following verse: يُخَادِعُونَ اللّهَ وَالَّذِينَ آمَنُوا وَمَا يَخْدَعُونَ إِلاَّ أَنفُسَهُم وَمَا يَشْعُرُونَ “Fain would they deceive God and those who believe, but they only deceive themselves, and realize (it) not!” [The Holy Qur’an al-Baqarah 2:9] Self as Viewed by the Qur’an As Sheikh Tabarsi said the Arabic word ‘ nafs’ meaning ‘self’ is used to mean the spirit or the soul as we can read in the following verse: اللَّهُ يَتَوَفَّى الْأَنفُسَ حِينَ مَوْتِهَا وَالَّتِي لَمْ تَمُتْ فِي مَنَامِهَا فَيُمْسِكُ الَّتِي قَضَى عَلَيْهَا الْمَوْتَ وَيُرْسِلُ الْأُخْرَى إِلَى أَجَلٍ مُسَمًّى إِنَّ فِي ذَلِكَ لَآيَاتٍ لِّقَوْمٍ يَتَفَكَّرُونَ “It is God that takes the souls (of men) at death; and those that die not (He takes) during their sleep: those on whom He has passed the decree of death, He keeps back (from returning to life), but the rest He sends (to their bodies) for a term appointed verily in this are Signs for those who reflect.” [The Holy Qur’an, al-Zumar 39:42] Another example where self is used to mean the soul is found in the following verse: وَاتَّقُواْ يَوْماً لاَّ تَجْزِي نَفْسٌ عَن نَّفْسٍ شَيْئاً وَلاَ يُقْبَلُ مِنْهَا شَفَاعَةٌ وَلاَ يُؤْخَذُ مِنْهَا عَدْلٌ وَلاَ هُمْ يُنصَرُونَ “Then guard yourselves against a day when one soul shall not avail another nor shall intercession be accepted for her, nor shall compensation be taken from her, nor shall anyone be helped (from outside).” [The Holy Qur’an, al-Baqarah 2:48] In another place, it is used to imply our soul or heart as in the following verses: وَاذْكُر رَّبَّكَ فِي نَفْسِكَ تَضَرُّعاً وَخِيفَةً وَدُونَ الْجَهْرِ مِنَ الْقَوْلِ بِالْغُدُوِّ وَالآصَالِ وَلاَ تَكُن مِّنَ الْغَافِلِينَ “And do thou (O reader!) Bring thy Lord to remembrance in thy (very) soul, with humility and in reverence, without loudness in words, in the mornings and evenings; and be not thou of those who are unheedful.” [The Holy Qur’an, al-A’raf 7:205] قَالُواْ إِن يَسْرِقْ فَقَدْ سَرَقَ أَخٌ لَّهُ مِن قَبْلُ فَأَسَرَّهَا يُوسُفُ فِي نَفْسِهِ وَلَمْ يُبْدِهَا لَهُمْ قَالَ أَنتُمْ شَرٌّ مَّكَانًا وَاللّهُ أَعْلَمْ بِمَا تَصِفُونَ They said: "If he steals, there was a brother of his who did steal before (him)." But these things did Joseph keep locked in his heart, revealing not the secrets to them.
