The issue of hereafter is totally different from our physical world. We see here with our eyes which is a ball of fat and flesh. Angels are an absolutely reality and they are intellect عقول therefore whenever we talk to see them it means not from the eyes which we have in this Duniya. Even we can’t beyond see the wall with these eyes. So please try to understand seeing Allah (swt) or Angels doesn’t mean with the eyes and its not referring to seeing their body because there is no case of physical body. All these discussions returns to our cognizant and Marifah as well as the Greatness of Allah (swt)
