Since September 2006, Siddiki has hosted a half-hour program on the Trinity Broadcasting Network called "Winning with Wisdom."
Siddiki, originally from Canada, was a marketing consultant executive at a financial services company before a bout with shingles in the 1980s, which he says sparked his conversion from Islam to Christianity.
[citation needed] Siddiki primarily serves as a motivational speaker at conferences for Christian businessmen, but has also published a book titled Kingdom Principles of Financial Increase and subsequent pamphlets and videotapes.
Siddiki has appeared with and been endorsed by Christian Ministers such as Benny Hinn, Rod Parsley (on his Breakthrough television program), and Kenneth Copeland.
On August 19, 2020, Nasir's second wife Anita Siddiki filed for divorce in Tulsa County, Oklahoma.
