Ali Ibn Abi Talib reported, "When I took possession of the weapon of the Messenger of Allah, peace be upon him, I found in the hilt of the sword a parchment saying, 'Keep relations with those who cut you off, behave well towards those who treat you badly, and speak the truth even if it is against yourself.'" [As-Saheehah of Abu Amr Ibnus Sammak]
Twentieth century media has tried to project Islam and Muslims as intolerant fundamentalists, but the truth of Allah's revelation stands clear from falsehood. This Hadith clearly directs the believers who will receive this legacy through Ameer-ul-Mumineen, Ali Ibn Abi Talib, to deal with all people in tolerance, forgiveness and truth.
This legacy, also, gives usa powerful lesson in conflict resolution. One of the greatest obstacles in the path of progress is disunity, but many of our differences and misunderstandings could be overcome if we would speak the truth at all times and recognize others if they are correct. Humility before Allah and others is not a weakness but a source of power that can cement our ranks and lead to healthy, fruitful relations.
