Narrated 'Abdullah bin Az-Zubair:
from his father who said: "When (the following) was revealed: 'Then, on the Day of Resurrection, you will be disputing before your Lord (39:31).' Az-Zubair said "O Messenger of Allah! We will repeat our disputes after what happened between us in the world?" He said: "Yes." So he said: "Indeed this is a very serious matter." (ES)
