helpless
in Edition Clear Qur'an by Talal Itani / An-Nisaa (The Women)

4:75And why would you not fight in the cause of God, and the helpless men, and women, and children, cry out, “Our Lord, deliver us from this town whose people are oppressive, and appoint for us from Your Presence a Protector, and appoint for us from Your Presence a Victor.”

4:127They ask you for a ruling about women. Say, “God gives you a ruling about them, and so does what is stated to you in the Book about widowed women from whom you withhold what is decreed for them, yet you desire to marry them, and about helpless children: that you should treat the orphans fairly.” Whatever good you do, God knows it.
