Musannaf Ibn Abi Shaybah

It is narrated from Hasan, he says that when the noble companions of the Messenger of Allah (peace be upon him) met each other, one man would say to his companion, "Have you received the news that you will enter (it)?" He would reply, "Yes." Then the first would ask, "Have you also received the news that you will exit from it?" He would reply, "No." Upon this, the first would say, "Then for what reason are you laughing?"
