This whole report is from an anti-Islamic website and lobby. First of all I am not saying that it does not happen and is not happening to this person (Yousef or Youcef, they are not even sure about his proper name) whatever his name is. But we are not sure that he has been held only for apostasy or something else? Then of course Iran has decided not to take dictation from USA & Co and as a result has been declared as one of the Axis of Evil so they have to portray Iran as bad as possible. Same Iran was apple of the eye for western countries just over 35 years ago for very well-known reasons.
However if nothing like that then still you may call it a law applied in a country.
As far as apostasy is concerned then nowhere in Quran it says that an apostate should be punished to death. However there are verses in Quran which speak opposite instead.
[Behold, as for those who come to believe, and then deny the truth, and again come to believe, and again deny the truth, and thereafter grow stubborn in their denial of truth — God will not forgive them, nor will guide them in any way.] (An-Nisaa' 4:137)
Please let me know how someone can believe, then disbelieve and then believe again if he is supposed to be killed the first time he disbelieve?
[And say [O Muhammad]: 'The truth [has now come] you're your Sustainer: let, then, him or her who wills, believe in it, and let him or her who wills, reject it.] (Al-Kahf 18:29)
