O handmaid of God! Once the hearts of men are purified, and their secret thoughts are cleansed, and their perception hath been freed of taint, then none will venture to perform any deed except such deeds as please the Lord. Nay rather, any action that is inconsistent with the high, God-given dignity of humankind, will seem to him an anguish more afflictive than hellfire, more terrible than eternal punishment in the bottomless pit.
At whatever time the heavenly Teachings are spread abroad, and their pillars are set firm and deep, and their walls raised up, and their rule is well established over the hearts, it is certain that man will not raise his hand against man to the point where such punishments as imprisonment, flogging, torment or the forfeiture of life would ever be called for. "And God sufficeth the believers in their fight.” [Qur'an 33:25] This verily is peace for all mankind, and complete tranquillity, and the highest perfection destined by God for man.
