Ali authored a 132-word blistering riposte to Islamophobes, in the light of remarks by the US presidential-hopeful, who has been chastised for claiming police in London "live in fear" of Muslim radicalisation.
He wrote in a message to fans that terror group Islamic State were "misguided murderers" and called on Muslims to stand up against "those who use Islam to advance their own personal agenda".
"I am a Muslim and there is nothing Islamic about killing innocent people in Paris, San Bernardino, or anywhere else in the world," Ali wrote.
"True Muslims know that the ruthless violence of so called Islamic jihadists goes against the very tenets of our religion.
"We as Muslims have to stand up to those who use Islam to advance their own personal agenda.
"They have alienated many from learning about Islam. True Muslims know or should know that it goes against our religion to try and force Islam on anybody.
"Speaking as someone who has never been accused of political correctness, I believe that our political leaders should use their position to bring understanding about the religion of Islam and clarify that these misguided murderers have perverted people's views on what Islam really is."
Ali's stinging intervention comes as the public backlash against Trump strengthens; a petition calling for the Republican frontrunner to be banned from Britain for "hate speech" attracted over 400,000 signatures in just two days.
One MP - Tasmina Ahmed-Sheikh - raised the issue in parliament on Wednesday, calling on the government to make Trump the 85th "hate preacher" barred from entering the country.
