The dangers of the grave and boastfully laughing...(hadith)

Abu Bakr al-Siddiq (radyAllahu`anhu) said, “He who enters the grave without any provisions is as though he wishes to sail the sea without a ship.” An ascetic once said, “The one who sins while laughing, Allaah will make him enter the Fire while crying. And the one who obeys while crying (out of fear of Allaah) Allaah will make him enter Paradise while laughing.”
