"The tenth indication" regarding the meanings of the prayers recommended for performance during celestial occurrences: such as lunar and solar eclipses, and the appearance of that which contradicts common habits in the sky, as well as the occurrence of fear on earth and drought due to the withholding of rain.

Know, O brother, that an eclipse according to the common folk is: a darkness that overcomes the light of the sun and the moon and removes it—and this is speech not to be concerned with. According to the astronomers, it is the meeting of the sun and the moon in a single zodiac sign and a single minute, such that the moon has no latitude separating it from the sun, and it is near one of the two nodes called the "Head" and the "Tail," so its body veils her body from the sights during their opposition, without any actual change occurring in the essence of the sun or the moon.

However, according to the people of the esoteric who are Knowers, this occurs as a warning of the dominance of the darkness of falsehood—which is the Accursed Opposite—over the person of the Gate (al-Bab) during the manifestation of the Veil through him.
