21:8
وَمَا جَعَلْنَاهُمْ جَسَداً لَّا يَأْكُلُونَ الطَّعَامَ وَمَا كَانُوا خَالِدِينَ
Nor did We give them bodies that ate no food, nor were they exempt from death.
21:34
وَمَا جَعَلْنَا لِبَشَرٍ مِّن قَبْلِكَ الْخُلْدَ أَفَإِن مِّتَّ فَهُمُ الْخَالِدُونَ
We granted not to any man before thee permanent life (here): if then thou shouldst die, would they live permanently?
26:128
أَتَبْنُونَ بِكُلِّ رِيعٍ آيَةً تَعْبَثُونَ

26:129
وَتَتَّخِذُونَ مَصَانِعَ لَعَلَّكُمْ تَخْلُدُونَ
"And do ye get for yourselves fine buildings in the hope of living therein (for ever)?
