Walid b Uqba a step brother of Uthman mourned on the death of Uthman in the following verses:
"What happened to this night,
It is so long and dreary. The stars have dimmed in their luster. O miscreants do not plunder the house of Uthman O Banu Hashim do not be in a hurry about assuming the caliphate ! Before us those who killed Uthman; And those whom they elevate to the caliphate
Are both guilty.
A river of blood flows between you and us,
By God I can never forget the tragedy of the assassination of Uthman;
How can a thirsty man be indifferent to the well?
They have killed Uthman so that they may succeed him;
We will fight against you.
O Muslims rise up to take revenge for the murder of Uthman.
If you hesitate you will not be your mother's son
The blood of Uthman cries for vengeance
And you must respond to the call.
"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
