@amrhima,
"Nietzsche's attempt to proclaim God dead results not only in the denial of truth, of science, but also of life."
If you bracket the Sufism and religious enthusiasm in the essay, and ignore some of the more gushing language, it might be worth reading, although I am not quite sure that some of the discussions about N's view of science due him justice.
For N., as the writer notes, the death of god is a
recognition of a nearly accomplished fact. N's view of science and of Truth is not
caused by his recognition that the Christian God (etc.) is no longer believable, but consistent with his challenging "philosophical prejudices" and commonly held absolutes.
Given Zarathustra's remarks about remaining true to the earth (and this world as opposed to some otherworldly one), and N's view that anything opposed to the enhancement of, or constituting a rejection of, Life must be viewed with suspicion or at least carefully
smelled for decay and disease, the essayist's conclusion about it and N. can only viewed as a
criticism from outside N's thinking.
Someone wishing to understand the thought of Nietzsche would be better served, I suggest, by reading more objective discussions by Kaufmann or Schacht.

John
