According to classical Islamic scholarship, the Quranic prohibition 'do not kill for fear of poverty' is a divine command that abolishes the pre-Islamic practice of infanticide. Tafsir of verses 6:151 and 17:31 by esteemed scholars like Ibn Kathir and Al-Qurtubi clarifies that this act is a grave sin, stemming from a lack of trust in Allah's promise of sustenance (rizq). The verses address both those currently in poverty and those who fear it in the future, assuring them that Allah provides for both parents and children. This concept underscores the sanctity of every child's life and highlights the mercy and providence of Allah, contrasting sharply with the ignorance and cruelty of the pre-Islamic era.
