Among numerous divine attributes, one is The Light, according to my belief. Arabic word for this attribute is Al-Nur. It means The One Who is apparent and Who makes other things evident and Who gives light to all.
Our inner light is due to God, as I understand. God sends holy prophets who spread divine light as His commandments. They alone stand up with moral message and forecast their victory. Against all odds they get success.
The Blessed Holy Prophet, according to Holy Quran, was best example upon whom light of God descended and who reflected light of God in all directions. His education did not lean to any side, it is balanced one, explains ahmadiyya caliph (w.mta.tv).
If the light of God does not reflect in believers attitudes, they ought to think where they lake. Light of God helps to understand rights of God, rights of people and rights of self through promised reforms.
