Exhorting the people to maintain unity, Uthman said:
"Remain united. Let there be no dissension in your ranks. You were the enemies of one another. God blessed you with Islam, and you began to love one another, and became brothers. Maintain your unity. Do not break up into sections. Allah is happy with your unity, and exhorts you to refrain from disunity."
"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
