Uthman introduced a few other measures as well to promote the purposes of Islam. On the occasion of the Friday prayers he introduced a second call or Takbir for the convenience of the people. He provided stipends for the first time for the 'Muezzins'. On the occasion of the Ramadhan, he increased the daily allowances of the people. He also arranged to supply free meals to all concerned at the time of the breaking of the fast. Uthman made special arrangement for the upkeep of mosques.
"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
