Translation:

5. O men! certainly the promise of Allah is true. Let not then this present life deceive you nor let the Chief Deceiver deceive you about Allah.

Notes (Tafseer)

3876. In verse 3 above the appeal was on the basis of the Past and the Present: now the appeal is on the basis of the Future. Allah's grace has promised us the Garden of Bliss; His justice has promised us the Fire of Suffering. Both promises are certain to be fulfilled. On which side shall we range ourselves?

3877. Cf. xxxi. 33 and n. 3624. The deception of Evil takes two forms. (1) The seductive temptations of this world may deceive us into forgetting the Hereafter. (2) The Arch-Enemy himself may so blind our vision that we may say with him, "Evil! be thou my good!" We may be misled by easy stages. Are we on our guard?
