Sahih Bukhari | Volume 8 | Hadith Number 475

Narrated by Anas bin Malik
Once Allah's Apostle led us in prayer and then (after finishing it) ascended the pulpit and pointed with his hand towards the Qibla of the mosque and said, "While I was leading you in prayer, both Paradise and Hell were displayed in front of me in the direction of this wall. I had never seen a better thing (than Paradise) and a worse thing (than Hell) as I have seen today, I had never seen a better thing and a worse thing as I have seen today."
