Tafsir of Ad-Dukhan 44:43-50

For the explanation of zaqqum, see E.N. 34 of Surah As-Saaffat.

The word al--muhl in the original has several meanings: molten metal, pus-blood, molten tar, lava, dregs of oil. These are the different meanings given by the lexicographers and commentators, but if this word is understood with reference to zaqqum (cactus), it may mean its juice which will probably be like the dregs of oil.
