Verse 57 of Sura 43 reads {43:57}: "And when the son of Mary is cited as an example, behold, the people jeer thereat".
According to traditions, the Holy Prophet is said to have told Ali one day that his example would be like that of Jesus Christ. A section of the people would love him so much that they would willingly die for him, while there would be some people who would fight against him.
"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
