If you will preach virtue, you will be among the virtuous. Counteract the evil with your tongue. Keep aloof from the wicked. Undertake Jihad in the way of God. In the affairs of God do not be afraid of the accusations of the evil mongers. For the vindication of the truth do not hesitate to face the storm of difficulties. Seek protection in faith.
"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
