Son, make yourself a balance between yourself and the people. Whatever you like for yourself, like it for others. Whatever is undesirable to you, consider it undesirable for others as well. If you do not want to be oppressed by any one, do not oppress anybody. Treat others as you wish to be treated by them. If the people behave with you as you behave with them, consider this to be a proper state of affairs. Do not say any thing without proper knowledge. Do not say anything, which you do not like to be heard against yourself.
"When a person dies, his works end, except for three: ongoing charity, knowledge that is benefited from, and a righteous child who prays for him."
Prophet Mohammed (PBUH)
"The best of what a man leaves behind are three: a righteous child who supplicates for him, ongoing charity the reward of which reaches him, and knowledge that is acted upon after him."
Sunan Ibn Mājah
"Every day two angels come down from Heaven and one of them says, 'O Allah! Compensate every person who spends in Your Cause,' and the other (angel) says, 'O Allah! Destroy every miser.'"
Sahih Bukhari
