It is narrated from Hazrat Abu Saeed (may Allah be pleased with him) that I was present with the Prophet (peace and blessings be upon him) at a funeral. There, the Prophet (peace and blessings be upon him) said: O people! This Ummah will also be tested in their graves. So, when a person is buried and his companions leave, an angel comes to him—who has a mace in his hand—makes him sit up and asks him about the Prophet (peace and blessings be upon him): "What do you say about this man?" If he is a believer, he says: "I bear witness that there is no god but Allah and that Muhammad (peace and blessings be upon him) is His servant and Messenger." Upon hearing this, the angel says: "You have spoken the truth." Then a door to Hell is opened and shown to him, and it is said: "If you had disbelieved in your Lord, this would have been your abode. But since you believed, your abode is elsewhere." Then a door to Paradise is opened for him. When he tries to get up and enter Paradise, the angel tells him to remain at ease, and his grave is made spacious for him.

And if he is a disbeliever or a hypocrite, when the angel asks him: "What do you say about this man?" he replies: "I do not know anything; I only heard people saying something." The angel says to him: "You neither understood nor recited nor were guided." Then a door to Paradise is opened and shown to him, and the angel says: "If you had believed in your Lord, this would have been your abode. But since you disbelieved, Allah has changed your abode from here," and a door to Hell is opened for him. Then the angel strikes him with his mace so forcefully that all of Allah's creation, except jinn and humans, hear its sound. Someone asked: "O Messenger of Allah! Will not anyone be terrified when an angel stands before him with a mace in his hand?" The Prophet (peace and blessings be upon him) said: "Allah keeps the believers firm on the word of Tawheed."
