I want to know the answer to the following question:
Who were 'Ali ibn Abi Talib and 'Abdullah ibn 'Abbas?
All the background I'm provided with is that "Other early exegetes included a few Companions of Muhammad, like ʻAli ibn Abi Talib, ʻAbdullah ibn Abbas, ʻAbdullah ibn Umar and Ubayy ibn Kaʻb.". Is that enough to answer the question?
