Our source of knowledge should be from Qur’an, The Prophet and Ahlul Bayt  (Peace and Blessings be upon Him and them). There are some people who thought that soul and spirit are same, but we read in Qur’an that soul is not the spirit and spirit is not the soul. 
    1.    Allah takes our souls when we sleep, and Allah sends it back when we wake up. Again, Allah takes our souls when we die than it will not be sent back after death except in Raj’aa. 
    2.    We don’t have in Qur’an that during death our spirit dies but our souls are being taken back by Allah (S.W.T.). 
    3.    While the spirit goes back to Allah. 
    4.    We have no details about the spirit because Allah has mentioned in Quran قل الروحُ مِ أمرِ رَبّي “Say the spirit matters belong to Allah"  (Sura 17, verse 85) means Allah only knows about the details of the spirit. We have very limited knowledge about the spirit. 
    5.    Soul can be good and can be medium and can be very good. It depends on the faith and deeds. We read in Qur’an about النفس آلأمّارة بالسوء Nafs Soul “Ammarah Bis_Soou’” which is ordering bad. Sura 12, verse 53.
    6.    There is another type of soul which is called Nafs Al “Lawwama” “the blaming soul” which blames the person when he or she does bad.  Sura 75, verse 2.
    7.    There is Nafs Al “Mutmaenna” the peaceful soul which is the soul of the most humble servants of Allah (S.W.T.). Sura 89, verse 27.
    8.    In Qur’an we read that the soul can be indulged in bad deeds and can be enjoying good deeds “Wa Nafsin Wa Ma Sawwaha Fa Al Hamha Fujuraha Wa Taqwaha”. Sura 91, verse 8.
    9.    Life and death are on the souls not on the spirit. Allah says “كُلُّ نَفسٍ ذائقةُ الموت ” Every soul will taste death.”Allah didn’t say every spirit will taste death. 
    10.    Soul is mentioned in Qur’an as the self when we say that myself, yourself that’s why Allah says in Qur’an “مَن عَمِلَ صالحاً فلنفسه” Whosoever does good he is doing good for himself. “ومن أساءَ فَعليها ” and whosoever does bad he is doing bad on himself. 
    11.    These are few differences between soul and spirit but we must admit that our knowledge of spirit is very much limited.   Wassalam.
