Allah mentions His servants who have Taqwa, obeying His orders, and avoid what He forbade:

[إِذَا مَسَّهُمْ]

(when comes to them) an evil thought, or anger, or the whispers of Shaytan cross their mind, or intend to err, or commit an error,

[تَذَكَّرُواْ]

(they remember) Allah's punishment, as well as, His tremendous reward. They remember Allah's promises and threats, then repent, go back to Him, seek refuge with Him and ask for forgiveness before death,

[فَإِذَا هُم مُّبْصِرُونَ]

(and (indeed) they then see (aright)) they become aright and aware of the error of their ways.
