Raf' ul-malaam 'an il-aïmmat il-a'laam - Ibn Taymiya

Al-Lajna ad-Da-ima said: "About the reasons for the divergence of scholars, many of them come from the fact that none of them had the whole knowledge. Thus, it is possible that one knows things that the other does not know, and can understand the texts differently from each other when clear evidence does not exist.

Sheikh ul-Islam Ibn Taymiyyah, may Allah have mercy on him, has extensively studied the issue in his book Raf'-ul-Malam. See it, and you will find what you are looking for if Allah wills."
