temporal nature of worldly life

حَتَّىٰٓ إِذَا جَآءَ أَحَدَهُمُ ٱلْمَوْتُ قَالَ رَبِّ ٱرْجِعُونِ

[For such is the state of the disbelievers] until, when death comes to one of them, he says, "My Lord, send me back

قُلْ يَوْمَ ٱلْفَتْحِ لَا يَنفَعُ ٱلَّذِينَ كَفَرُوٓا۟ إِيمَـٰنُهُمْ وَلَا هُمْ يُنظَرُونَ

Say, [O Muḥammad], "On the Day of Conquest the belief of those who had disbelieved will not benefit them, nor will they be reprieved."
