and (sometimes, S, Msb) كِرْسِىٌّ (S, Msb, K) A throne; synonym سَرِيرٌ: (K:) a chair: (TK:) a seat not larger than is sufficient for one person: (Bd, ii. 256:) [and a stool:] plural كَرَاسِىٌّ (S, Msb, K) and sometimes كَرَاسٍ, agreeably with a rule mentioned by ISk. (Msb.) It is the place [or seat] of the king, and of the learned man: and hence, as used in the Qur'an, 2:256, it is explained as signifying (tropical:) Dominion: (A:) and (tropical:) the power of God, whereby He holds the heavens and the earth: (TA:) and (tropical:) knowledge: (A, K:) which last explanation is ascribed to I'Ab: but the truth is, that I'Ab explained it as there signifying the [foot-stool of God; or] place of the feet: but as to the عَرْش [of God], this is immeasurable: (Az, TA:) or it signifies the sphere of the stars. (TA, article عرش.) [Hence, also, you say,] هُوَ مِنْ أَهْلِ الكُرْسِىِّ (tropical:) He is of the people of science. (TK.) [And hence,] الكَرَاسِىُّ is also used [elliptically] to signify (tropical:) The learned men; according to Ktr. (A.)
