(TA.)

I. q. ضَرَرٌ (assumed tropical:) [Harm, injury, &c.]: so in the phrase لَا بَأْسَ [There is, or will be, no harm, &c.; and لَا بَأْسَ بِكَذَا, and فِى كَذَا, (assumed tropical:) There is, or will be, no harm in such a thing]. (Har p. 311.) It is said in a tradition, لَا بَأْسَ بِالْغِنَي لِمَنِ اتَّقَي [There is no harm in wealth to him who is pious]. (El-Jámi' es-Sagheer of Es-Suyootee.) بَاس also occurs for بَأْس; the being suppressed, agreeably with analogy; not altered by permutation. (M, TA.)
