An-Nisa 4:92 وما كان لمومن ان يقتل مومنا الا خطا ومن قتل مومنا خطا فتحرير رقبة مومنة ودية مسلمة الى اهله الا ان يصدقوا فان كان من قوم عدو لكم وهو مومن فتحرير رقبة مومنة وان كان من قوم بينكم وبينهم ميثاق فدية مسلمة الى اهله وتحرير رقبة مومنة فمن لم يجد فصيام شهرين متتابعين توبة من الله وكان الله عليما حكيما ٩٢

٩٢
It is not lawful for a believer to kill another except by mistake. And whoever kills a believer unintentionally must free a believing slave and pay blood-money to the victim’s family—unless they waive it charitably. But if the victim is a believer from a hostile people, then a believing slave must be freed. And if the victim is from a people bound with you in a treaty, then blood-money must be paid to the family along with freeing a believing slave. Those who are unable, let them fast two consecutive months—as a means of repentance to Allah. And Allah is All-Knowing, All-Wise.

The Ruling Concerning Killing a Believer by Mistake
Allah states that the believer is not allowed to kill his believing brother under any circumstances. In the Two Sahihs, it is recorded that Ibn Mas`ud said that the Messenger of Allah ﷺ said,
«لَا يَحِلُّ دَمُ امْرِىءٍ مُسْلِمٍ يَشْهَدُ أَنْ لَا إِله
