لزب

لَازِبٌ ذ Adhering, or adhesive, or cohesive, clay or mud. (S.) ― -b2- Being, or remaining, fixed, settled, firm, or constant. (S.) ― -b3- صَارَ الشَّىْءُ ضَرْبَةَ لَازِبٍ The thing became fixed, settled, firm, or constant, (S, K,) and severe: (TA:) [or, a constant infliction: ] or, indispensable, or necessary: i. e., the blow of a sword that sticks, or remains fixed, [ in the wound ]. (Aboo-Bekr, cited in the TA.) لازب is here the same as لازم: (K:) the latter is the original word; the م being changed into ب; and is also used in this phrase: (TA:) but لازب, in this in- stance, is the more chaste. (S.) En-Nábighah says, فَلَا تَحْسِبُونَ الخَيْرَ لَا شَرَّ بَعْدَهُ وَلَا تَحْسِبُونَ الشَّرَّ ضَرْبَةَ لَازِبِ [ Then think ye not that good shall have no evil after it, nor think ye that evil shall be a constant infliction ]. (S.) Sgh says, of the conversion of رِوَاغَةٌ into رِيَاغَةٌ, or of و into ى because of kesreh before it, هٰذَا القَلْبُ لَيْسَ بِضَرْبٍ لَازِبٍ [ This conversion is not a necessary sort. ] (TA in art. روغ.)
