The Qur'an says that all Muslims are brothers[^43] and have great love and affection among themselves.[^44] No excuse should be allowed to stand in the way of doing good or making peace between different persons.[^45] Every effort should be made to bring about con­ciliation between men,[^46] yet we should co‑operate in righteousness and piety, not in sin and rancour.[^47] We should be kind to those in need, to neighbours, and to the wayfarers.[^48] This attitude, of kindness and fairness is to be maintained and upheld even in the case of enemies and opponents.[^49] We should try to forgive those who plot against us and overlook their deeds,[^50] cover evil with pardon,[^51] and turn off evil with good.[^52] This attitude of toleration is to be cultivated in our relation to people of other faiths.

The Qur'an aims at establishing a peaceful social atmosphere where people belonging to other faiths can enjoy freedom of conscience and worship[^53] for which purpose the believers are urged to rise and fight against the oppressors so that monasteries, churches, synagogues, and mosques in which the name of God is commemorated in abundant measure may not be pulled down.[^54] It unreservedly praises some of the people of the Book for their faith.[^55] It is as a consequence of this attitude of tolerance that according to the Qur'an all those who believe in God and the Last Day and practice right­eousness, whether they are Muslims, Jews, Christians, or Sabaeans, shall get their reward from their Lord.[^56] The Qur'an gives an open invitation to the people of the Book to come together and work conjointly for the establishment of peace and social harmony based on the idea of the unity of God.[^57] Above all, this ideal of unity leads to the conception of unity of the whole of humanity.
