“And We granted not to any human being immortality before you (O Muhammad); then if you die, would they live forever?”
[al-Anbiya’ 21:34]
“Whatsoever is on it (the earth) will perish.
And the Face of your Lord full of Majesty and Honour will remain forever”
[al-Rahmaan 55:26,27]
“Verily, you (O Muhammad) will die, and verily, they (too) will die”
[al-Zumar 39:30]
