Uthman issued the following directive for the general public:
"Know that whatever you have attained is due to Islam and following the injunctions of the Holy Prophet. If you are lost in the world you will betray the objective of your life. Follow Islam faithfully and do not introduce any innovations. See that the abundance of wealth does not divert you from the ideals of Islam. The extension of your dominions has brought various peoples within your fold. See that this does not lead to any differences among you. Remain united. Hold fast to the rope of God. May God bless you."
"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
