Rauf was withdrawn last week because Indian police are investigating his performances in the Indian Premier League.
"I personally deny all the news coming from the media ... regarding spot-fixing, match-fixing, taking gifts and money," Rauf said in Lahore on Wednesday.
"I tell you one thing very clearly that, throughout my life, money and gifts do not matter to me."
Rauf, on the International Cricket Council's elite panel of umpires since 2006, said if the governing body constituted any hearing against him, he would appear before it.
"I am happy to answer any questions," he said.
Rauf was caught up in the spot-fixing scandal in the just-concluded IPL, during which Indian police arrested three Rajasthan Royals players, Chennai Super Kings official Gurunath Meiyappan and several bookmakers.
Rauf said the ICC withdrew him from the upcoming Champions Trophy because the scandal could have distracted his performance in the eight-team event.
Rauf was scheduled to officiate in a warm-up match between Australia and West Indies on Saturday in Cardiff, Wales, and two group matches: Sri Lanka vs. New Zealand on June 9 and West Indies vs. South Africa on June 14, both in Cardiff.
"I am satisfied with the ICC's decision to withdraw me because it may cause distraction while performing my role amid allegations," he said.
"They only withdrew me from the Champions Trophy and not fired me so it was their decision with my consent for the betterment of me and the cricket."
Rauf, 58, has supervised in 48 tests, 98 one-day internationals and 23 Twenty20s.
