Universal peace and harmony is an ideal system for all men around the world. Conflicts between countries have pushed nations into great wars, but now the world is realizing that war is not the solution to any of the problems and also that justice for everyone is very important to maintain peace around the world. The creation of United Nations also shows the importance and a way forward to maintain peace and harmony around the world. Islam, a true religion, especially focuses upon peace and harmony through justice. Our holy Prophet (peace be upon him) is a role model for everyone in the world. Through his actions and deeds, he taught us how to resolve conflicts peacefully. The placement of Hijra-e-Aswat in Khana-e-Kaba was peacefully resolved through his (PBUH) wisdom. Forgiving his (PBUH) worst enemies after "Fatah-e-Makkah" is yet another example of peace and justice. Several initiatives from United Nations have been proved successful in resolving conflicts around the world but true justice and proper implementation of United Nations resolutions is still to be ensuring by all countries. Being a Muslim, it is also our religious duty to contribute towards universal peace and harmony. But all of us must remember that real peace and harmony around the world is only possible through true justice.
