It is recorded in the traditions on the authority of Ibn Umar that the Holy Prophet said that the angels stood abashed before Uthman as they stood abashed before God and His Apostle. It is recorded on the authority of Hasan that about the modesty of Uthman the Holy Prophet said: "If it were that .Uthman was in the middle of his house, and the door was closed upon him, and he were to put aside his clothes to pour water upon himself, modesty would prevent him to straighten his back."
"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
