Allah Almighty has created everything for some purpose. Nothing is created without a determination or aim. No doubt, there is some purpose of our existence too. As sun is created to light up the day similarly, the aim of our life should also be to illuminate others life. It is said: "Everyone lives for himself but the true human being is he who lives for others". Although, we can't light up the whole globe but at least we can illuminate our surroundings with the power of our knowledge. We all should make our self like a candle who burns itself but give light to others.
