And hence, because enmity is kindled with it like as fire is with حَطَب [properly so called], (Har p. 209,) (tropical:) Calumny, or slander; (A, Mgh, TA;) also termed الحَطَبُ الرَّطْبُ. (TA.) The former is said to have this meaning in the Qur'an, 111:4: (Mgh, TA:) or to mean thorns, which the woman there spoken of is related to have been in the habit of throwing in the way of Mohammad. (TA.) You say, يَحْمِلُ
الحَطَبَ بَيْنَ النَّاسِ, meaning (tropical:) He goes about
with calumny, or slander, among, or between, the people. (A.)

the latter is explained by ISh as meaning the prunings that are cut off each year from the upper, or uppermost, portions of a grape-vine. (TA.)
