The Promised Messiah (peace be upon him) wrote:
“True taqwa is accompanied by a light, as Allah, His eminence be glorified, has said:
يٰۤاَيُّهَا الَّذِيْنَ اٰمَنُوْۤا اِنْ تَتَّقُوا اللّٰهَ يَجْعَلْ لَّكُمْ فُرْقَانًا وَّ يُكَفِّرْ عَنْكُمْ سَيِّاٰتِكُمْ / وَ يَجْعَلْ لَّكُمْ نُوْرًا تَمْشُوْنَ بِهٖ
“This means, ‘O you who believe, if you remain steadfast in piety and firmly establish the quality of taqwa for the sake of Allah, then Allah will place a distinction between you and others. This distinction is that you will be granted a light by which you will walk in all your paths—meaning, this light will permeate all your actions, words, faculties, and senses. Your intellect will be illuminated, and even your intuitive thoughts will be filled with radiance. There will be light in your eyes. In your ears, in your tongues, in your speech, and in your every movement and stillness, there will be light. The paths you tread will become illuminated. In short, all your paths—the paths of your faculties and senses—will be filled with light, and you will walk immersed in light from head to toe.”
