In Islamic theology, 'Materialism' is understood not as a philosophical belief in matter, but as the spiritual disease of **Hubb al-Dunya** (the love of the worldly life), which prioritizes material possessions and comforts over spiritual values and the Hereafter. According to search-discovered classical scholarship, authorities like Imam Al-Ghazali explain that this attachment is a primary veil that corrupts the heart and leads to heedlessness (ghaflah). The Quran addresses this theme extensively across 33 key verses, most notably in Surah At-Takathur, which condemns the 'rivalry in worldly increase' that distracts humanity until death. Tafsir Ibn Kathir, synthesizing these verses, consistently interprets the accumulation of wealth and children not as blessings in themselves, but as a profound trial (**fitna**) from Allah to test one's obedience and gratitude. This comprehensive understanding does not prohibit earning wealth but warns against the spiritual poison of allowing its pursuit to become the ultimate purpose of life, thereby causing one to lose the eternal reward of the Hereafter.
