Surah An-Nisa Ayahs #97 Translated in English

But whoever kills a believer intentionally - his recompense is Hell, wherein he will abide eternally, and Allāh has become angry with him and has cursed him and has prepared for him a great punishment.

O you who have believed, when you go forth [to fight] in the cause of Allāh, investigate; and do not say to one who gives you [a greeting of] peace, "You are not a believer," aspiring for the goods of worldly life; for with Allāh are many acquisitions. You [yourselves] were like that before; then Allāh conferred His favor [i.e., guidance] upon you, so investigate. Indeed Allāh is ever, of what you do, Aware.

Not equal are those believers remaining [at home] - other than the disabled - and the mujāhideen, [who strive and fight] in the cause of Allāh with their wealth and their lives. Allāh has preferred the mujāhideen through their wealth and their lives over those who remain [behind], by degrees. And to all [i.e., both] Allāh has promised the best [reward]. But Allāh has preferred the mujāhideen over those who remain [behind] with a great reward -

Degrees [of high position] from Him and forgiveness and mercy. And Allāh is ever Forgiving and Merciful.

Indeed, those whom the angels take [in death] while wronging themselves - [the angels] will say, "In what [condition] were you?" They will say, "We were oppressed in the land." They [the angels] will say, "Was not the earth of Allāh spacious [enough] for you to emigrate therein?" For those, their refuge is Hell - and evil it is as a destination.
