Son, you are born for the Hereafter. Death lies in wait for you. Howsoever you may run from it, it will overreach you. You have to fall a victim to death sooner or later. Therefore be careful lest death comes to you before you have had the opportunity to repent. In that case you will be deemed to destruction. Son, you should be well prepared so that when death comes you have no regret.
"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
