"Woe to those... who, when they have to receive by measure from men, exact full measure, but when they have to give by measure or weight to men, give less than due."
Qur'an, Surah 83, The Unjust
"O mankind! Surely We have created you from a male and a female and made you tribes and families that you may know each other. Surely the noblest among you in the sight of God is he who is the most righteous of you."
"In the name of God, I put my trust in God and there is no strength and no power except with God. O God, I seek refuge with You lest I should stray or be led astray, lest I slip or be tripped, lest I oppress or be oppressed, lest I behave foolishly or be treated foolishly."
