ذُكَاءُ
1.
, imperfectly decl., The sun: (S, K:) determinate, and not admitting the article ال: you say, هٰذِهِ ذُكَاءُ طَالِعَةٌ [This is the sun rising]: (S:) derived from ذَكَتِ النَّارُ. (TA.)
2.
Hence, (S,) اِبْنُ ذُكَاءَ
The dawn, or daybreak: (S, K:) because it is from the light of the sun. (S.) Homeyd says, [or, according to some, Besheer Ibn-En-Nikth, as in one of my copies of the S, in article كفر,]
[And she, or they, came to the water before the bright shining of the daybreak, while the dawn lay kid in the darkness of night]. (S.)فَوَرَدَتْ قَبْلَ انْبِلَاجِ الفَجْرِوَابْنُ ذُكَاءَ كَامِنٌ فِى الكَفْرِ
