No worldly punishment is mentioned for apostasy:

4. Sura Nisa [Medina]

Ali’s version and the Quranic text

وَمَن يُشَاقِقِ الرَّسُولَ مِن بَعْدِ مَا تَبَيَّنَ لَهُ الْهُدَى وَيَتَّبِعْ غَيْرَ سَبِيلِ الْمُؤْمِنِينَ...   

4:115. If anyone contends with the Messenger even after guidance has been plainly conveyed to him, and follows a path other than that becoming to men of faith,

... نُوَلِّهِ مَا تَوَلَّى وَنُصْلِهِ جَهَنَّمَ ....

We shall leave him in the path he has chosen, and land him in Hell,

.. وَسَاءتْ مَصِيرًا ﴿١١٥﴾

what an evil refuge?

Asad’s version:

4: 115 But as for him who, after guidance has been vouchsafed to him, cuts himself off from the Apostle and follows a path other than that of the believers – him shall We leave unto that which he himself has chosen, and shall cause him to endure hell: how evil a journey’s end!
