Know well that the friends (saintly servants) of God – they will have no fear (both in this world and the next, for they will always find My help and support with them), nor will they grieve
No doubt! Verily, the Auliya of Allah (i.e. those who believe in the Oneness of Allah and fear Allah much (abstain from all kinds of sins and evil deeds which he has forbidden), and love Allah much (perform all kinds of good deeds which He has ordained)), no fear shall come upon them nor shall they grieve,
Know with certainty! There will be no fear for the guardians (waliyy) of Allah, nor will they be grieved.
Sayyed Abbas Sadr-Ameli
Behold! Verily no fear shall be upon the friends of Allah, nor shall they grieve;
Al-muntakhab fi tafsir al-Qur'an al-Karim
Indeed, those whose hearts have been touched with the divine hand who chose to be under Allah's tutelage are they who are safe and secure; they have no ground for alarm nor shall fear or dread fall upon them, nor shall they come to grief
