According to Google, the three major world religions in the world are Christianity (33%), Islam (20.1%), and Hinduism (13.3%). My collection of principles common to these three and the others as well are the following:-
Sense of Community
From the Islamic Sunnah: “No one of you is a believer until he desires for his brother that which he desires for himself”.
Jewish Talmud, says: “What is hateful to you, do not do to your fellow man”
Hindu Mahabharata declares: “This is the sum of duty; do naught onto others what you would not have them do unto you”.
Christian’s Old Testament says: “And as ye would that men should do to you, do ye also to them likewise.”
Compassion for others
“The truly good are those who believe in God and the last day, the angels, the scripture, the prophets, who give away some of their wealth, however much they cherish it, to relatives, to orphans, to needy, the traveller and beggar and to liberate those in debt and bondage (Al Quran 2:178)
Buddha’s words are, “Go your ways, oh monks, for the benefit of many, for the happiness of many, out of compassion for the world, for the good, benefit and happiness of gods and men”.
The Bible also preaches, “If there is a needy person among you…do not harden your heart and shut your hand against your needy kinsman.”
“Founder of Sikh religion Baba Guru Nanak said “if you want to meet God, serve the poor people,”
Respect for freedom of thought and expression
Islam: “You are not a dictator over them. So remind, with the Qur’an, whoever fears My Threat. “(Surah Qaf, 45);
Christianity: “It is in accordance with their dignity as persons-that is, beings endowed with reason and free will and therefore privileged to bear personal responsibility-” (Second Vatican Council, Declaration on Religious Freedom, 2)
Judaism: “Just as people’s faces are not the same, so their opinions are not the same; everyone has their own opinion” (Numbers Rabbah, Pinhas, 21.2)
Buddhism: “The ultimate authority must always rest with the individual’s own reason and critical analysis.” (Dalai Lama)
Hinduism: “Let noble thoughts come to us from all sides.” (Rig Veda)
“Mindfulness,” or Prayers
“Those who keep up the prayers and pay the prescribed alms; who keep pledges whenever they make them; who are steadfast in misfortune, adversity and times of danger. These are the ones who are true, and it is they who are aware of God. (Al Quran 2:178)
The Hindu Svetesvatara Upanishad recommends the “quiet retreat of Yoga”:
And Jesus told his followers: “Take therefore no thought for tomorrow: for tomorrow shall take thought of the things for itself”
Accountability for your actions – Sins
Buddhism teaches: “All beings are the owners of their deeds (karma), the heirs of their deeds”.
In the Bible Job 4:8 says, “As I have observed, those who plow evil and those who sow trouble reap it.”
“On those who believe and do good works, there shall be no sin for what they eat, provided they fear God and believe and do good works (Al Quran 5:94)
Judaism acknowledges sin as violations of God’s commandments. Each of these is a black entry in the ledger that may outweigh the red.
Justice and Fair play
Quran 5:8 (Asad) “bearing witness to the truth in all equity, and never let hatred of anyone lead you into the sin of deviating from justice”
Bible in Hosea 12:6 says, “But you must return to your God; maintain love and justice, and wait for your God always”
Moses PBUH said, “Decide justly [tzedek] between each man and his brother or a stranger. You shall not be partial in judgment. Listen to great and small alike. Fear no one.”
