And whatever you have been given is only a temporary provision of this life, but that which is with Allah is better and more lasting for those who believe and put their trust in their Lord, And who eschew the more grievous sins and indecencies, and, when they are wroth, they forgive, And those who hearken to their Lord, and observe prayer, and whose affairs are decided by mutual consultation, and who spend out of what We have provided for them, And those who, when a wrong is done to them, defend themselves.
Islam, The Holy Qur’an, 42:37-40
Moses, son of Imran said, ‘My Lord, who is the greatest of Thy servants in Thy estimation?’ and received the reply, ‘The one who forgives when he is in a position of power.’
Islam, The Holy Prophetsa,Hadith of Baihaqi
On account of his weak nature, he deserves that at the time of any slipping, if he should repent and seek forgiveness, God’s mercy should save him from being ruined. It is a certainty that if God had not been the Acceptor of repentance, man would not have been charged with these hundreds of commandments. This proves conclusively that God turns towards man with mercy and is Most Forgiving.
Islam, The Promised Messiahas, Chashma-e-Ma’rifat,Ruhani Khaza’in, Vol. 23, p. 192-193
You shall not take vengeance or bear any grudge against the sons of your own people, but you shall love your neighbor as yourself: I am the Lord.
If you are offering your gift at the altar, and there remember that your brother has something against you, leave your gift there before the altar and go; first be reconciled to your brother, and then come and offer your gift.
Christianity, The Bible, Matthew 5:23-24
Who takes vengeance or bears a grudge acts like one who, having cut one hand while handling a knife, avenges himself by stabbing the other hand.
Judaism, Jerusalem Talmud, Nedarim 9:4
Where there is forgiveness, there is God Himself.
Sikhism,Adi Ganth, Shalok, Kabir, p. 1372
