Forgive has great importance in Islam. Quran has many verses on Forgiveness.
Islam teaches us to forgive people. Islam speak about two types of forgiveness (a) Allah's forgiveness (b) Human's forgiveness We need both forgiveness because human are fallibility. Forgiveness form Allah Almighty : In Quran, the word “Allah is Most Merciful” is repeated many times. In religion Islam, anyone who has committed sin can ask forgiveness directly from Lord, there is no one between Allah and the one who is asking forgiveness from Him. In Quran, Allah says: “God loves those who turn unto Him in repentance and He loves those who keep themselves pure.” From this verse, we can conclude that if someone asked forgiveness with repentance then Allah will love him/her and surely He will forgive him/her but there is one condition and that is he/she should not commit that sin or mistake again. Forgiveness from Human beings : If someone did wrongs to another human being, the act must first be redressed with the wronged person or human being who should be asked for forgiveness before asking forgiveness from Allah. Islam teaches human beings to be forgiving and if someone sincerely asks for forgiveness, the wronged person should forgive him. Our beloved Prophet (SAW) said: “Whoever suffers an injury and forgives (the person responsible), God will raise his status to a higher degree and remove one of his sins.” If we expect forgiveness from Almighty Allah then we also have the ability to forgive others.
