Uthman always had a great fear of God. He exhorted the functionaries of the State to fear God and do justice to all concerned. In his sermons Uthman always exhorted the people to do good deeds which could stand them in good stead in the world hereafter. Whenever Uthman passed a graveyard he would weep bitterly. When asked to explain the reason for his weeping he said that he had heard the Holy Prophet say that. the grave was the first stage to the next world, and if that stage passed off peacefully, there would be little trouble at the succeeding stages.
"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
