He has created us in such a way that we have a proper vessel that can contain this special bit of energy and it has no adverse effects of any kind on the carrier. One of our purposes of us being in this world is to ‘charge up’ this spark of light just as a power pack is charged up via electricity. Every soul is like a power pack that needs to be fully charged. If this is achieved when the soul is reunited with the body on the Day of Judgment it will be a full source of energy that will enlightened the body. In relation to this Allah says in Surah Imran;
‘On the Day when some faces will be (lit up with) white’. (3:106)
We need to charge up this power pack and keep it bright and shinning to reflect the Light of Allah on earth; and if this is achieved the light of that soul will permeate the cells of the body. When this happens the fire of hell will not be able to burn such a body since the light of the soul is much more intense than hell fire.
If you keep at it and allow the light of the soul to keep the body bright and shinning you will be a special person. As Allah says in His Words ‘on the Day when some faces will be white’. Prophet Muhammad [u.w.b.p] was able to cultivate his light to such an extent that his personality was constantly bright, so much so that the light of the sun was less in comparison to his light. This is possibly why his body never cast a shadow, because the light that his personality reflected was greater and brighter than any other sources of light such as the sun.
His Companions testified to this on numerous occasions. For example Aisha (ra) swore by Allah that his face was brighter than that of a full moon. How fortunate indeed were these Companions, to have a little glimpse of this blessed and unique personality.
It is reported in ahadith that if a person is blessed with a vision of Prophet [u.w.b.p] that person will not enter Jahanam. Islamic Spirituality teaches us that we can establish a conscious relationship with him. If you develop yourself properly you can have vision of him. But first you have to work hard. You need to activate and develop the spiritual points of the body and thereafter you can make contact with the spiritual personality of Prophet .
Work continuously to build the energy of your soul so that when it rejoins the body you will be amongst the blessed ones to have a brightened countenance, and you will be fit to meet your Lord and enter into the Garden. Work hard to polish your soul so that its light will permeate every cell of the body. Satan’s mission is to put the dark spots around the soul to block out the energy / light; so remain focus and committed through the adversities.
Let us make a conscious effort, every single day, to make right the conditions surrounding us that will allow our ruh to grow and spread. We beg Allah to make this exercise easy for us and may He keep us far away from the heedless ones and the ones who understand not. May Allah bless us and protect us.
