Hatim was succeeded by his son Adi. Adi tried to follow in the footsteps of his father. He tried to be generous and munificent but he could not attain that fame that had been earned by his father. Adi was very religious in his own way, and was very particular in the worship of idols in the local temple. When Islam came to spread to the neighboring tribes, Banu Tai showed a hostile attitude to Islam. Thereupon the Holy Prophet sent an expedition to Banu Tai under the command of Ali.
"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
