Love Thy Neighbor

Thou shalt love thy neighbor as thyself. There is none other commandment greater than these.

Thou shalt not avenge, nor bear any grudge against the children of thy people, but thou shalt love thy neighbor as thyself.

And you should forgive and overlook: do not like God to forgive you? And Allah is The Merciful Forgiving.

...

Love one another and you will be happy.
It is as simple and as difficult as that ...
