Sa'ad b Abi Waqas was not able to repay the loan within the stipulated period, and lbn Masud insisted on immediate repayment. Sa'ad b Abi Waqas wanted an extension in the time for the repayment of the loan. Ibn Masud refused to allow any extension ~n the ground that in accordance with the terms of the grant of the loan no extension was admissible. The issue became the subject matter of a dispute between Ibn Masud and Sa'ad b Abi Waqas. Hot words were exchanged between the two highest functionaries in the province. In the dispute some persons sided with Ibn Masud while some persons favored Sa'ad b Abi Waqas. Such differences created a crisis, and the provincial administration came to be paralyzed.
"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.'"
