The Mihrab
Interpreters mention that praying in a mihrab (prayer niche) in a dream at an unconventional time signifies future goodness for the dreamer's descendants. Urinating in the mihrab with drops indicates the birth of several noble and prominent sons, as the mihrab fundamentally symbolizes a leading imam. Furthermore, a minaret represents a man who gathers people for good, and its collapse signifies his death and obscurity.
