Quran 4:94 — Women (Al-Nesa')

O you who believe, if you strike in the cause of GOD, you shall be absolutely sure. Do not say to one who offers you peace, "You are not a believer," seeking the spoils of this world. For GOD possesses infinite spoils. Remember that you used to be like them, and GOD blessed you. Therefore, you shall be absolutely sure (before you strike). GOD is fully Cognizant of everything you do.

[4:93] Anyone who kills a believer on purpose, his retribution is Hell, wherein he abides forever, GOD is angry with him, and condemns him, and has prepared for him a terrible retribution.

[4:95] Not equal are the sedentary among the believers who are not handicapped, and those who strive in the cause of GOD with their money and their lives. GOD exalts the strivers with their money and their lives above the sedentary. For both, GOD promises salvation, but GOD exalts the strivers over the sedentary with a great recompense.
