Abu Sa'eed narrated:
The Messenger of Allah (s.a.w) entered his Musalla and saw the people who looked as if they were smiling. So he said: 'Indeed, if you were to increase in remembrance of the severer of pleasures, then you would find yourselves too busy for what I see. So increase in remembrance of death, the severer of pleasures. For indeed there is no day that comes upon the grave except that it speaks, saying: I am thee house of the estranged, I am the house of the solitude, I am the house of dust, and I am the house of the worm-eaten. When the believing worshipper is buried, the grave says to him: Welcome, make yourself comfortable. Indeed, to me, you are the most beloved of those who walked upon me. Since you have been entrusted to me and delivered to me today, you shall see what I have arranged for you. It will then widen for him so that his sight extends, and the door to Paradise is opened for him. And when the wicked worshipper or the disbeliever is buried , the grave says to him: You are not welcome, do not get comfortable. Indeed, to me, you are the most hated of those who walked upon me. Since you have been entrusted to me and delivered to me today, you shall see what I have arranged for you.' He said: 'It will begin closing in on him(squeezing him) until his ribs are crushing each other.' He said: The Messenger of Allah (s.a.w) clasped some of his fingers between others and said: 'Seventy giant serpents will constrict him, if even one of them were to hiss on the earth, nothing upon it would grow as long as it remained. They will chew on him and bite him until he is brought to the Reckoning.' He said: The Messenger of Allah (s.a.w) said: 'The grave is but a garden from the gardens of Paradise, or a pit from the pits of the Fire.'
