Star Names
The Auspice of the Slaughterer (sa’d adh-dhabih)
The Auspice of the Slaughterer is one of the ten Auspicious Asterisms (as-su’ud). The Arabic term indicates good fortune or something that is auspicious, especially a star. The Auspicious Asterisms are all pairs of otherwise unremarkable stars, except for one that is comprised of four stars. The Auspice of the Slaughterer is a pair of moderately-bright stars, one of which has a faint star very close to it that was called the Sheep (ash-shat), the one that is about to be slaughtered.

Ibn Qutayba (d. 879 CE) reported that the Auspice of the Slaughterer was said to rise on the morning of January 18 and set on the morning of July 18. On account of the precession of the equinoxes, today we can expect to observe the Auspice of the Slaughterer setting in early-August and rising in early February, as seen from the latitude of Tucson.
