The physicist Abdus Salam, in his Nobel Prize banquet address, quoted a well known verse from the Quran (67:3-4) and then stated: "This in effect is the faith of all physicists: the deeper we seek, the more is our wonder excited, the more is the dazzlement of our gaze". One of Salam's core beliefs was that there is no contradiction between Islam and the discoveries that science allows humanity to make about nature and the universe. Salam also held the opinion that the Quran and the Islamic spirit of study and rational reflection was the source of extraordinary civilizational development. Salam highlights, in particular, the work of Ibn al-Haytham and Al-Biruni as the pioneers of empiricism who introduced the experimental approach, breaking way from Aristotle's influence, and thus giving birth to modern science. Salam was also careful to differentiate between metaphysics and physics, and advised against empirically probing certain matters on which "physics is silent and will remain so," such as the doctrine of "creation from nothing" which in Salam's view is outside the limits of science and thus "gives way" to religious considerations.
