Eleven years later, Parwez was overthrown by his second son Sheeruya. Parwez was first put in the dungeon, and later blinded and killed. Sheeruya had all royal princes killed except his son Ardsheer. As Yazdjurd remained in hiding, he escaped from the massacre. To avoid discovery, Yazdjurd moved from Seestan to Persepolis. Sheeruya the regicide could hold the throne for a short period of six months only. He was succeeded by his son Ardsheer who also ruled for a short time. Thereafter there was a succession of some princesses. Their rule was also short-lived. In the absence of any other prince, Yazdjurd was discovered and crowned in 632 C.E. He was a young man of twenty-one at the time
"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.'"
