Principle Of Awl (inheritance Law)
A kalam in clear langauge is one things and its understanding is another. It is likely that humans may commit mistake in understanding a problem written in a clear language. This happens in every field of knowledge. It is authentic that Umar started Awl and it was accepted by all, except for Abdullah bin Abbas, but since he was younger as compared to his elders, he did not made his opinon loud. Sahabe sometimes differed with each other on the understanding of a verse or problem. Such examples are found in the literature of tafsir of Quran.
