Yedi Yıldızın Ahkamı

The Provisions of the Seven Stars is a work written by Sheikh Vefa Hazretleri (Muslihuddin Mustafa) in the 15th century. The work was copied approximately one hundred years after the death of its author. The work provides information on how the planets affect certain times of the day, which tasks are considered auspicious or may have negative consequences at certain times, and which tasks are appropriate or inappropriate to undertake on different days of the month.
