It was narrated that az-Zubair bin al-"Awwam (رضي الله عنه) said:

When this surah was revealed to the Messenger of Allah (ﷺ): "Verily, you (O Muhammad is) will die, and verily, they (too) will die. Then, on the Day of Resurrection, you will be disputing before your Lord” (az-Zumar [39:30,31]), az-Zubair said: “O Messenger of Allah, will we face again the disputes we had among us in this world in addition to other sins?” He said: “Yes, you will face these disputes again until everyone who has a right has been given his right.” AzZubair said: “By Allah, the matter is very serious.”
