Abu Umamah reported: The Messenger of Allah, peace and blessings be upon him, said, “O son of Adam, it is better for you to spend in charity. To withhold is evil for you, yet there is no blame if you do so out of necessity. Begin spending on your dependents, for the upper hand that gives is better than the lower hand that takes.”

Doing good for others is really a good manner or behave.
Nowdays,people around us most of them become selfish when they find anything good for them.They really dont know that giving hand is Always upper or respectful then taking hand.
If you do good to others it will come back to u in any days when u are in need.
