Praying (Salah)
Quick Answer
Fulfillment of promises, answering of prayers, and reaching one's goals.
Classical Interpretation (Ibn Sirin)
Performing obligatory prayers (Salah) in a dream perfectly and completely is one of the best dreams. It signifies the fulfillment of a promise, attaining authority, and the answering of one's prayers. Praying in the wrong direction (not Qibla) shows deviation from the truth. Praying while sitting without an excuse indicates that one's deeds might not be accepted.
Quranic Context
"Indeed, prayer prohibits immorality and wrongdoing... (Quran 29:45)"
