Sa'd al Suud is the twenty-fourth lunar mansion, spanning roughly 295 to 308 degrees within Aquarius. Its name means the luckiest of the fortunate ones, reckoned the most auspicious of the sa'd mansions. In the manazil tradition its planetary ruler is Jupiter, and its traditional talismanic virtue is marriage and victory, favourable for weddings and for triumph over rivals. Each of the manazil carries a fixed magical property from the Arabic tradition, transmitted through the Picatrix and Agrippa for the timing of talismans. These are the conventions of that talismanic tradition rather than statements about the stars, which here are the group in Aquarius that the twenty-eight-mansion scheme counts at this station of the Moon in its monthly circuit through the ecliptic.
Sa'd al Suud, reckoned the luckiest of the sa'd group and, by extension, sometimes described in the medieval sources as the most fortunate of all twenty-eight manazil, anchors its virtue of marriage and victory to a reputation that outlasted the specific talismanic tradition recorded in the Picatrix, surfacing also in general medieval Arabic folk astrology as a byword for good luck independent of the mansion scheme's formal magical apparatus. Its identification with stars in Aquarius is less secure in the surviving sources than the identification of the brighter manazil elsewhere in the series, a recurring caveat for several of the fainter stations clustered through this stretch of the zodiac.
