They will say: "It was you who used to come to us from the right side [i.e. from the right side of one of us and beautify for us every evil, order us for polytheism, and stop us from the truth i.e. Islamic Monotheism and from every good deed]."
They will say, "Indeed, you used to come at us from the right."
(37:28) (The followers will say to their leaders): 'You used to come to us from the right hand.' *18
*18) The word yamin in Arabic is used for several meanings. It may mean use of the force, or well-wishing, or swearing of an oath. Accordingly, the verse would mean: (1) "You compelled us into following error and deviation"; or (2) "you deceived us by posing as our well-wishers"; or (3) "you swore oaths to satisfy us that what you were presenting was the very trnth."
