(Yaaseen) 36 : 48
وَيَقُولُونَ مَتَىٰ هَٰذَا الْوَعْدُ إِنْ كُنْتُمْ صَادِقِينَ

And they are asking: “When this promise will happen if you are so truthful?”

The hypocrites ask this question to the believer who says that this worldly life—this fourth phase of life—is the cultivation ground for the Hereafter. See explanation 7:187; 32:29; 35:37-38.
