Do not kill your children

وَلَا تَقْتُلُوا أَوْلَادَكُمْ خَشْيَةَ إِمْلَاقٍ نَّحْنُ نَرْزُقُهُمْ وَإِيَّاكُمْ إِنَّ قَتْلَهُمْ كَانَ خِطْئًا كَبِيرً

Hence, do not kill your children for fear of poverty: it is We who shall provide sustenance for them as well as for you. Verily, killing them is a great sin 17:31
