Is God's answering a disbeliever's prayer considered proof of his disbelief, based on the Hadith which indicates that God does not like to hear the voice of a disbeliever?

Allah answers the prayers of those who supplicate, and the answer is more pronounced for Muslims than for disbelievers. Allah Almighty says: "And when My servants ask you concerning Me, then I am indeed near. I respond to the invocation of the supplicant when he calls upon Me. So let them respond to Me and believe in Me, that they may be guided." And in the Hadith: "The supplication of Dhun-Nun when he supplicated with it while he was in the belly of the whale: 'None has the right to be worshiped but You; glory be to You, indeed I have been of the wrongdoers.' No Muslim man supplicates with it concerning anything ever, except that he is answered." Therefore, the answering of prayers is an indication of good, not of evil. As for the mentioned Hadith, nothing has been found to confirm its authenticity.
