Ibn Sina or Avicenna is one of the greatest Muslim philosophers that left indelible impressions on the Western Philosophy. Not only that Avicenna had contributed immensely to the field of medicine, which continues to benefit the field of modern medicine. Although he comes from today's Uzbekistan, which is part of Central Asia, he is generally considered to be a great scholar of the Persian world.
My question is mainly to the Sunni Muslims. Whether ibn Sina's [Avicenna] religious views are compatible with the Quranic teachings or not. Which ones agree and which ones do not with the teachings of the Quran? why?
