Prophet Abraham left Egypt accompanied by his nephew Lot , who then went to the city of Sodom (Sadum), which was on the western shore of the Dead Sea.
This city was filled with evil. Its residents waylaid, robbed and killed travelers. Another common evil among them was that men had sex with men instead of with women. This unnatural act later became known as sodomy (after the city of Sodom). It was practiced openly and unashamedly.
"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
