Five years passed away and by that time Parwez had forgotten all about the prediction. Availing of the opportunity, Shirin told him about the birth of a grandson. He expressed the desire to see the child. The child was brought and Parwez became fond of him. After some time Parwez recalled the prediction and decided to kill the child. Shirin pleaded for the life of the child. Parwez ultimately agreed to spare the life of the child, provided he was exiled away from the court. Yazdjurd was accordingly exiled to Seestan.
"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
