Having taken the decision to open the campaign by a march on Basra, the confederates issued a proclamation in the following terms: "The Mother of the Faithful, Talha and Zubair, two eminent companions of the Holy Prophet, are leading an army to Basra and whosoever has any spark of faith in him should join the ranks to defend the faith, and fight to seek vengeance for the blood of Othman. Those who do not have the means of the journey will be provided with conveyance, arms and other necessities. It is an obligation on the part of the Muslims to rise to vindicate the truth. "
"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.'"
