Islam may seem exotic or even extreme in the modern world. Perhaps this is because religion does not dominate everyday life in the West today, whereas Muslims have religion always uppermost in their minds, and make no division between secular and sacred. They believe that the Divine Law, the Shari'a, should be taken very seriously, which is why issues related to religion are still so important.
"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
