It was narrated that Abu Umaamah al-Baahili (may Allaah have mercy on him) said: I heard the Messenger of Allaah (peace and blessings of Allaah be upon him) say: “Whilst I was sleeping, two men came to me and took me by the arms, and they brought me to a mountain and said: ‘Climb up.’ I said: ‘I cannot.’ They said: ‘We will make it easy for you.’ So I climbed up until, when I was at the top of the mountain, I heard loud voices. I said: ‘What are these voices?’ He said: ‘These are the cries of the people of Hell.’ Then they took me on, and I saw some people hanging by their heels, with the sides of their mouths torn, and the sides of their mouths were flowing with blood. I said: ‘Who are these?’ He said: ‘They are the ones who broke the fast before it was permissible for them to do so.’” Narrated by Ibn Hibbaan and al-Haakim (1/210, 290); classed as saheeh by al-Albaani in al-Saheehah (3951).
