One billion people from a vast range of races, nationalities and cultures across the globe--from the southern Philippines to Nigeria--are united by their common Islamic faith. About 18% live in the Arab world; the world's largest Muslim community is in Indonesia; substantial parts of Asia and most of Africa are Muslim, while significant minorities are to be found in the Soviet Union, China, North and South America, and Europe.
"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
