And who are not guilty of fornication. His punishment shall be doubled unto him on the day of resurrection; and he shall remain therein, covered with ignominy, for ever
Burning will be multiplied for him during Doomsday and he will abide forever in disgrace (abandoned, alone).
Sayyed Abbas Sadr-Ameli
On the Day of Judgment, the chastisement will be doubled to him, and he shall abide therein in abasement
Al-muntakhab fi tafsir al-Qur'an al-Karim
His punishment shall be doubled in Day of Judgement when he will have passed through nature to eternal suffering incensed by multiplied wrongs and humiliations
And those who do not pray to another (presumed) god along with Allah, and do not kill any person whose (killing) Allah has forbidden except in (the cause) of truth, and they do not commit adultery and whoever does that, he will meet (the punishment of his) sin.
