Muslims believe in One, Unique, Incomparable God; in the Angels created by Him; in the prophets through whom His revelations were brought to mankind; in the Day of Judgement and individual accountability for actions; in God's complete authority over human destiny and in life after death. Muslims believe in a chain of prophets starting with Adam and including Noah, Abraham, Ishmael, Isaac, Jacob, Joseph, Job, Moses, Aaron, David, Solomon, Elias, Jonah, John the Baptist, and Jesus, peace be upon them. But God's final message to man, a reconfirmation of the eternal message and a summing-up of all that has gone before was revealed to the Prophet Muhammad (SAW) through Gabriel.
"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
