Now as to the froth, or scum, it passeth away as a thing that is worthless, or useless, or unprofitable], (Fr, S, Jel, TA,) and thrown away. (Jel.) You say also, ذَهَبَ الزَّبَدُ جُفَآءً, meaning [The froth, or scum, passed away] driven from its water. (TA.) b3: جُفَآءٌ مِنَ النَّاسِ, occurring in a trad., is explained by IAth as meaning The first, or foremost, of the men or people (سَرَعَانُهُمْ): but Bkh and Muslim read (instead of جفاء) أَخِفَّآءُ, pl. of خَفِيفٌ. (TA.) A2: Also, [like جُفَايَةٌ,] An empty ship. (O, K.)
