Allah (SWT) says in The Holy Qur'an:

"Never will I allow to be lost the work of any of you, be he male or female. You are (members) one of another, so those who emigrated and were driven out from their homes, and suffered harm in My Cause, and who fought, and were killed (in My Cause), verily, I will expiate from them their evil deeds and admit them into Gardens under which rivers flow (in Paradise); a reward from Allah, and with Allah is the best of rewards." (3:195) - Surah Al-Imran : Ayah 195
