Apostasy in Islam taken place. Justifications offered for the alleged executions vary, but one of the most common theories advanced is that they were in retaliation for the 1988 attack on the western borders of Iran by the PMOI Mujahedin. However, this does not fully account for the targeting of other leftist groups who opposed the Mujahedin invasion. Salman Rushdie is a prominent contemporary figure accused of apostasy. In 1989 a fatwa was issued by Ayatollah Khomeini, the ruler of Iran at the time, calling for the death of Salman Rushdie for the blasphemy of authoring the book "The Satanic Verses". Hossein Soodmand,
Salman Rushdie that he still receives a "sort of Valentine's card" from Iran each year on 14 February letting him know the country has not forgotten the vow to kill him and has jokingly referred it as "my unfunny Valentine" in a sly reference to the song "My Funny Valentine". He said, "It's reached the point where it's a piece of rhetoric rather than a real threat." Despite the threats on Rushdie personally, he said that his family has never been threatened, and that his mother, who lived in Pakistan during the later years of her life, even received outpourings of support.
