Lighting the lamp of a mosque signifies a righteous and devout child.
Seeing and lighting many lamps signifies religion and piety; extinguishing them signifies deprivation of religion and piety.
Seeing a burning lamp in one's own house go out is interpreted in two ways: the end of one's life, or the death of a male child. Jabir al-Maghribi said that lighting an oil lamp with a flint or match signifies marriage for the unmarried and a child for the married. If the dreamer has someone away from home, it also signifies that person's safe return.
Ibn Sirin said that seeing many lamps burning signifies a just king, an ascetic scholar, and a beneficial judge.
Seeing a lamp burning also signifies an increase of light in the heart, strength in religion, and attainment of one's desire.
