According to search-discovered classical Islamic scholarship, the term 'Firewood' (الحطب - al-hatab) in the Quran transcends its literal meaning to become a profound symbol of divine punishment and the consequences of malicious deeds. The primary context, found in Surah Al-Masad regarding the wife of Abu Lahab, is explained by authorities such as Ibn Kathir and Al-Qurtubi to signify the act of spreading slander and discord, which is likened to gathering firewood to fuel a fire of conflict. This metaphorical understanding is directly linked to its eschatological reality presented in both Surah Al-Masad and Surah Al-Jinn (72:15), where the unjust themselves become the literal fuel or 'firewood' for Hellfire. Thus, the Quranic concept of 'hatab' masterfully connects sinful actions in this world, particularly malicious speech, to their tangible and terrifying consequences in the Hereafter.
