Seeing oneself worship Allah Most High signifies attaining the good of this world and the Hereafter. Glorifying Allah Most High and mentioning His blessed name signifies moving from sorrow to relief, release from grief and distress, and purification from sins.
Ja'far al-Sadiq said that a dream of worship is interpreted in five ways: nearness to Allah Most High, entering the best path, glad tidings, victory over an enemy, and deliverance and safety. Finishing the prayer, seeking forgiveness from Allah Most High, and turning toward the qibla signifies that one's prayers will be accepted and one's spiritual rank elevated. Remembering the Lord by saying 'Subhanallah, Subhanallah' signifies the departure of sorrow and grief from a direction one did not expect. Praising Allah, Mighty and Majestic, signifies attaining guidance and light in religion. Giving thanks to Allah Most High signifies strength, abundant blessing, and, for one qualified for it, becoming governor of a city.
