طِبَاقٌ

[a plural of طَبَقَةٌ, and said to be also a plural of طَبَقٌ].

طِبَاقُ الأَرْضِ means What is upon the earth: (S, O:) or what fills, or would fill, the earth, extending over it in general, or in common, (O, TA,) as though it were a طَبَق [or cover] to it. (TA.) It is said in a tradition respecting Kureysh, عِلْمُ عَالِمِهِمْ طِبَاقُ الأَرْضِ i. e. The knowledge of the knowing of them is as though it extended over the earth in general, or in common, and were a cover to it; (O, * TA;) or, as some relate it, الأَرْضِ طِبْقُ. (TA.)
