He, (May the blessing and peace of God be upon him), was eager to deal with his neighbors in a high way. He used to ask about a neighbor if he did not see him. He used to visit him if he was ill. He used to share him his happiness, he used to support him at times of sorrow and he used to do him good.
He appointed a neighbor the right that made him about to be a member of his family who deserves to inherit him. He, (May the blessing and peace of God be upon him), said: "Gabriel kept recommending me about neighbor until I thought he will appoint him a part of the inheritance." .
As for his enemies, he, (May the blessing and peace of God be upon him), never had any rancor, spite or malice towards them. When he knew the people of Mecca who were severely fighting him, were rainless and had starvation, he sent them 500 camels loaded with food and other things. He, (May the blessing and peace of God be upon him), never initiated war with people but he was only defending himself.
He was sent as a caller to guidance, when his people offended him severely, his companions asked him to supplicate God to destroy them, he, (May the blessing and peace of God be upon him), said: "I was never sent as insulter but I was sent as mercy" .
He, (May the blessing and peace of God be upon him), was so kind and merciful to his enemies. He used to say to his soldiers: "I recommend you to fear God, don’t disobey God, don’t be false to your trust, don’t be cowards, don’t destroy a monastery, don’t cut palm trees, don’t fire plants, don’t kill animals, don’t cut fruit trees, don’t kill an old man, a child or a woman, you will see people stay in hermitages, let them do what they devoted themselves for" .
I.e. they only fight fighters, even when they fight people who fight them, he recommended them not to initiate war with them, not to betray, not to torture or distort their bodies and organs after killing them. He used to respect the dead people among his enemies. Once a funeral passed him, he stood at once, they said: It is the funeral of a Jewish, he said: "Isn't it a soul?" .
We see that the messenger (May the blessing and peace of God be upon him), was the best example of tolerance, care and good manners even with his enemies (May the blessing and peace of God be upon him).
