— those who fear their Lord: people of wakeful hearts who remember that they must one day stand before Him, having shed every relative who could support them and every mediator who might intercede for them in His presence without His permission. Such remembrance may move them to prepare for that encounter, so that in this life they perform deeds by which Allah will save them from His punishment on the Day of Resurrection.

Relevance of the verse to this chapter: it rebuts the idolaters who call upon prophets and righteous men, seeking their intercession.

Points gleaned from the verse:

1. A refutation of those polytheists who seek to draw near to prophets and saints by asking them for intercession.
2. The legitimacy of preaching and reminding people of the Day of Judgment.
3. It is only believers who truly benefit from admonition.
