Uncertain about and afraid of death are only such people as are ignorant about themselves and about life as an all-pervading miracle. Since the other half of existence is death, it is hardly surprising why those who in vain try to ignore and suppress death are never truly content or at peace.
Definitely, without death on-board, neither life can be fully optimized and enjoyed. No genuine existential victories can be associated with half-life.
Those backward people, as a result, will never stop inventing myriads of untruths and superstitions about dying and death, and of course about life as a whole. Believers should never fall prey to such follies. Believers’ Allah-given providence, dignity and worth are so exalted that they in no way can be reconcilable with the ideological nonsense of the modern nihilistic and hedonistic man.
Finally, life without death would be meaningless and incomplete. Moreover, it would be fake and unnatural. Only death can make life valuable and truly enjoyable. It can make it real.
''Every soul will have a taste of death, and you will receive your recompense on the Day of Resurrection. Whoever is swayed from the Fire, and admitted to Paradise, has won. The life of this world is merely enjoyment of delusion''. (Surah Ali Imran, 185)
