The 51-year-old singer - whose full name is now Shuhada' Davitt - then questioned Twitter's policy about blocking hateful content, as she wondered whether or not her account would be deleted. In a tweet this morning, the singer revealed that she never wants to "spend time with white people again (if that's what non-Muslims are called)".
"What I'm about to say is something so racist I never thought my soul could ever feel it".
She posted the comments online, but prefaced them by saying "I'm terribly sorry". "Not for one moment, they are truly disgusting", she tweeted. "And its [sic] ALL EQUALLY IRELLEVANT [sic] TO OUR TIMES", she wrote.
"This is to announce that I am proud to have become a Muslim", she explained to her Twitter followers.
Sinead took to social media last month to announce her change of faith, and said the conversion was the "natural conclusion of any intelligent theologian's journey".
"Dear Sister, whoever is "teaching" you about Islam, seems to be trying to lead you astray".
In a series of bold tweets, Davitt spoke on her belief in wome and her disgust for Donald Trump and his administration, stating sometimes you have to match fire with fire.
O'Connor's most recent tweet on the matter read, "Final word. Which makes all other scriptures redundant", the Grammy victor added, before revealing she would henceforth be known by a new name. She has also openly spoken about past abortions - a contravention of Canon Law.
