In his elegy Aiman b Hazim said:
"The people conspired to murder Uthman
They shed the blood of the Caliph in the sacred city of the Holy Prophet. They have betrayed Islam.
His murderers have forfeited the right to be called Muslims They stand condemned before man and God; The murderers of Uthman stand cursed; And grievous will be their end."
"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
