The Prophet (ﷺ) led us in prayer and then went up to the pulpit and beckoned with both hands towards the
Qibla of the mosque and then said, "When I started leading you in prayer, I saw the display of
Paradise and Hell on the wall of the mosque (facing the Qibla). I never saw good and bad as I have
seen today." He repeated the last statement thrice.
