Those who do not believe in their eternal life to come deviate from that straight way.
Sayyed Abbas Sadr-Ameli
And verily those who do not believe in the Hereafter are deviating from the Way
Al-muntakhab fi tafsir al-Qur'an al-Karim
But those who deny Resurrection and Judgement Hereafter never deviate into sense. On the contrary, they deviate themselves from the path of righteousness
