اِرْتِسَامٌ
1.
[in its primary sense, as quasi-pass. of رَسْمٌ, verbal noun of رَسَمَ, is apparently post-classical, but, as such,] is used by the logicians as meaning The being stamped and depicted [in the mind]: (“ Dict. of the Technical Terms used in the sciences of the Musalmans: ”] an image's being fixed in, or upon, a thing. (KL.) [It is used, in this sense, of an image formed by the fancy, and of any ideal image.]
2.
[Also (tropical:) The obeying a prescript or command &c.] You say, رَسَمْتُ لَهُ كَذَا, (S, K,) or بِكَذَا, (Msb,) فَارْتَسَمَ, (Msb, K,) or فَارْتَسَمَهُ, (S,) (tropical:) [I prescribed to him the doing of such a thing; or] I commanded, ordered, bade, or enjoined, him to do such a thing, (K, TA,) and he obeyed (S, Msb, TA) it [i. e. the prescript &c.]. (S, Msb.) And
أَنَا أَرْتَسِمُ مَرَاسِمَكَ (tropical:) [I obey thy prescripts &c.;] I do not transgress thy
مراسم. (TA.)

And hence, (TA,) ارتسم signifies also (tropical:) He said
اَللّٰهُ أَكْبَرْ [God is great, or most great]: (S, M, K, TA:) and he sought protection or preservation [by God]: (M, K, TA;) and he prayed or supplicated or petitioned [God]: (S, K:) as though [meaning] he took the course prescribed by God, of having recourse to Him for protection or preservation. (TA.) El-Aashà says, [speaking of wine,]
(S, M, TA,) or وَأَقْبَلَهَا, (so in some copies of the S in this article and in article صلو, and in the Mgh, also, in the latter article,) i. e. [And he exposed it to the wind, in its jar, and he prayed over its jar,] and petitioned for it (TA in this article and in article صلو) that it might not become sour, nor spoil: (TA in the latter article:) AHn says that ارتسم means he stamped its vessel with the رَوْسَم; but this saying is not valid: (M, TA:) [and Mtr, also, says that] ارتسم, here, is from الرَّوْسَمُ, and means he stamped it. (Mgh in article صلو.)وَصَلَّى عضلَى دَنِّهَا وَارْتَسَمْوَقَابَلَهَا الرِيحَ فِى دَنِّهَا
