Is killing a person haram?

Haram Family & relations Quran · 3 Hadith · 1

Short answer

Yes. The Quran says that whoever kills a soul unjustly, it is as if he had killed all mankind (5:32), and forbids killing the soul that Allah has made sacred except by right (6:151, 17:33). The Prophet ﷺ said that blood shed is the first matter judged between people.

Quran

مِنْ أَجْلِ ذَٰلِكَ كَتَبْنَا عَلَىٰ بَنِىٓ إِسْرَٰٓءِيلَ أَنَّهُۥ مَن قَتَلَ نَفْسًۢا بِغَيْرِ نَفْسٍ أَوْ فَسَادٍۢ فِى ٱلْأَرْضِ فَكَأَنَّمَا قَتَلَ ٱلنَّاسَ جَمِيعًۭا وَمَنْ أَحْيَاهَا فَكَأَنَّمَآ أَحْيَا ٱلنَّاسَ جَمِيعًۭا ۚ وَلَقَدْ جَآءَتْهُمْ رُسُلُنَا بِٱلْبَيِّنَٰتِ ثُمَّ إِنَّ كَثِيرًۭا مِّنْهُم بَعْدَ ذَٰلِكَ فِى ٱلْأَرْضِ لَمُسْرِفُونَ ﴿٣٢﴾

For that cause We decreed for the Children of Israel that whosoever killeth a human being for other than manslaughter or corruption in the earth, it shall be as if he had killed all mankind, and whoso saveth the life of one, it shall be as if he had saved the life of all mankind. Our messengers came unto them of old with clear proofs (of Allah's Sovereignty), but afterwards lo! many of them became prodigals in the earth.

۞ قُلْ تَعَالَوْا۟ أَتْلُ مَا حَرَّمَ رَبُّكُمْ عَلَيْكُمْ ۖ أَلَّا تُشْرِكُوا۟ بِهِۦ شَيْـًۭٔا ۖ وَبِٱلْوَٰلِدَيْنِ إِحْسَٰنًۭا ۖ وَلَا تَقْتُلُوٓا۟ أَوْلَٰدَكُم مِّنْ إِمْلَٰقٍۢ ۖ نَّحْنُ نَرْزُقُكُمْ وَإِيَّاهُمْ ۖ وَلَا تَقْرَبُوا۟ ٱلْفَوَٰحِشَ مَا ظَهَرَ مِنْهَا وَمَا بَطَنَ ۖ وَلَا تَقْتُلُوا۟ ٱلنَّفْسَ ٱلَّتِى حَرَّمَ ٱللَّهُ إِلَّا بِٱلْحَقِّ ۚ ذَٰلِكُمْ وَصَّىٰكُم بِهِۦ لَعَلَّكُمْ تَعْقِلُونَ ﴿١٥١﴾

Say: Come, I will recite unto you that which your Lord hath made a sacred duty for you: That ye ascribe no thing as partner unto Him and that ye do good to parents, and that ye slay not your children because of penury - We provide for you and for them - and that ye draw not nigh to lewd things whether open or concealed. And that ye slay not the life which Allah hath made sacred, save in the course of justice. This He hath command you, in order that ye may discern.

وَلَا تَقْتُلُوا۟ ٱلنَّفْسَ ٱلَّتِى حَرَّمَ ٱللَّهُ إِلَّا بِٱلْحَقِّ ۗ وَمَن قُتِلَ مَظْلُومًۭا فَقَدْ جَعَلْنَا لِوَلِيِّهِۦ سُلْطَٰنًۭا فَلَا يُسْرِف فِّى ٱلْقَتْلِ ۖ إِنَّهُۥ كَانَ مَنصُورًۭا ﴿٣٣﴾

And slay not the life which Allah hath forbidden save with right. Whoso is slain wrongfully, We have given power unto his heir, but let him not commit excess in slaying. Lo! he will be helped.
