tbh I've read Kierkegaard and enjoyed/learn a lot from him. Even with western philosphy, although it is always secular, a muslim can learn quite a bit from them.
Naturally no book comes even close to the wisdom of the Quran, but with western philosphy one can still learn quite a few things from it.
Even Nietzsche, although an aetheist, his philosphical musings do have some merit, especially from the Islamic perspective. For example, while life itself is inhernetly meaningless, the worldy life for the sake of itself is meaningless (i.e. without religion, there is no meaning).
So tbh I say read Kierkegaard, but keep in mind that what he says (or any philospher) is not the be-all-end-all. Just keep the Quran nearest to your heart, and take the good from the books you read, and leave the bad
