post-classical. See what next follows.]
4 ارسب It caused [a thing] to sink: hence, in a
trad., describing the people of Hell, إِذَا طَفَتْ بِهِمُ النَّارُ أَرْسَبَتْهُمُ الأَغْلَالُ When the fire shall raise them, and make them. to appear [or rather to swim upon its surface], the collars, by reason of their weight, shall make them to sink to the bottom thereof. (

رَسُوبٌ [What is wont to sink, or subside, in water &c.
b2: And hence,] Dregs amid water and blood: in this sense improperly pronounced رُسُوبٌ. (

M,
A,
K) that penetrates into, (

K) and ↓ رُسَبٌ (
K,
TA) and ↓ مِرْسَبٌ. (
A,
K,
TA. [In the
