(18) باب الْقَصْدِ وَالْمُدَاوَمَةِ عَلَى الْعَمَلِ
Narrated Anas bin Malik:
Once Allah's Messenger (ﷺ) 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."
