Surah Isra': 31 (killing of children is haram)

In the name of Allah, The Most Gracious, The Most Merciful.

وَلاَ تَقْتُلُواْ أَوْلادَكُمْ خَشْيَةَ إِمْلَـقٍ نَّحْنُ نَرْزُقُهُمْ وَإِيَّاكُم إنَّ قَتْلَهُمْ كَانَ خِطْئًا كَبِيرًا
"And kill not your children for fear of poverty. We shall provide for them as well as for you. Surely, the killing of them is a great sin." (Surah Isra': 31)

Lessons:
- Allah is more compassionate towards His servants than a father to his child, because He forbids killing children just as He enjoins parents to take care of their children in matters of inheritance. The people of Jahiliyyah would not allow their daughters to inherit from them, and some would even kill their daughters lest they make them more poor.
- Always remember that Allah is The Provider, The Sustainer. Your job is just a Blessing and means bestowed by Allah SWT to the provisions you enjoy.
- We should not think that we are self-sufficient, and think we can take decisions for yourself. Allah is The One who plans and wills.
- This ayah is not just talking about killing of children literally. It is also implying that abortion is haram.

And Allah knows best.
