Prophet Muhammad once said:
“The highest form of worship is to pray as if you were seeing God.”
We learn from this Hadith, The highest form of worship is for man to sense the presence of God during worship, and feel that he has come close to God. His eyes are moist with tears. He starts receiving inspiration from God, at that time he can experience the refreshing, cooling effect of God’s love and blessings for him. It is this feeling of closeness to God which is the highest form of worship.
