Read and reflect on verse 2923 from Surah Al-Furqaan: and who never invoke any [imaginary] deity side by side with God, and do not take any human beings life - [the life] which God has willed to be sacred...
وَالَّذِينَ لَا يَدْعُونَ مَعَ اللَّهِ إِلَٰهًا آخَرَ وَلَا يَقْتُلُونَ النَّفْسَ الَّتِي حَرَّمَ اللَّهُ إِلَّا بِالْحَقِّ وَلَا يَزْنُونَ ۚ وَمَنْ يَفْعَلْ ذَٰلِكَ يَلْقَ أَثَامًا
and who never invoke any [imaginary] deity side by side with God, and do not take any human beings life - [the life] which God has willed to be sacred - otherwise than in [the pursuit of] justice, and do not commit adultery. And [know that] he who commits aught thereof shall [not only] meet with a full requital
