About the advent of real amity and enmity in judgement Day, many koranic verses are revealed, some them as follows:
Once the trumpet is blown, no ties of kinship will exist between them not that day, not may they question one another. (23:101) when then uproar comes on a day when man will flee from his brother his mother and his father , his mate and his children , every hast man among them will have enough concern that day to keep him occupied (80:33-37)
On that day even bosom friends will become one another enemies unless they have done their duty. (43:67)
