A scholar says that death is not the punishment for a murtad.

Answer

The punishment for a murtad here on earth is that he will be arrested in an Islamic country. He will be given three days to reflect, and the Ulama will engage him in an endeavour to remove his doubts to enable him to repent and re-embrace Islam. If he refuses, then after three days, he will be executed. In the Hereafter the punishment is everlasting perdition in Jahannum. The person who denies this Shar'i law is not a scholar. He is a moron.
