The Study and understanding of the Quran should not be restricted to the limited criteria of time. This is because time comes and goes. The methods of thinking and pondering also change. The value and importance of things are also not stable. They rise and fall. If a particular philosophy is born in a particular time, or a particular definition or connotation is laid down (in a particular time), it is not necessary that the very same philosophy or definition be totally applicable in the era or in the next generation. The Quran is Divine book. It is independent. It possesses its own personality. Maulana Abul Hasan Ali Nadwi Rahmatullahi Alayh
