سنن ابن ماجہ #4267

It was narrated that Hani’ the freed slave of ‘Uthman bin ‘Affan, said:“When ‘Uthman bin ‘Affan stood beside a grave, he would weep until his beard became wet. It was said to him: ‘You remember Paradise and Hell, and you do not weep, but you weep for this?’ He said: ‘The Messenger of Allah (ﷺ) said: “The grave is the first stage of the Hereafter. Whoever is delivered from it, what comes after it is easier. If he is not delivered from it, then what comes after it is harder.’” He said that the Messenger of Allah (ﷺ) said: “I have never seen any horrible scene but the grave is more horrible.”
