جُفَاءٌ

What is cast forth [of froth, or foam, and particles of rubbish or refuse, (see 1,)] by a torrent: (ISk, S:) the froth, or foam, cast forth by a valley [flowing with water]; and by a cooking-pot, (K, TA,) in boiling. (TA.)

Hence, as being likened to the froth, or foam, of the cooking-pot, of which no use is made, (Fr, TA,) i. q. بَاطِلٌ [meaning A thing that is worthless, useless, or unprofitable]. (Fr, K, TA.) It is said in the Qur'an, 13:18, فَأَمَّا الزَّبَدُ فَيَذْهَبُ جُفَاءً, meaning بَاطِلًا [i. e. 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 جُفَاءً, meaning [The froth, or scum, passed away] driven from its water. (TA.)

جُفَاءٌ مِنَ النَّاسِ, occurring in a tradition, is explained by IAth as meaning The first, or foremost, of the men or people (سَرَعَانُهُمْ): but Bkh and Muslim read (instead of جفاء) أَخِفَّاءُ, plural of خَفِيفٌ. (TA.)

-A2- Also, [like جُفَايَةٌ,] An empty ship. (O, K.)
