Fires in a number of majority-black churches followed the shooting of nine people inside the Emanuel African Methodist Episcopal Church in Charleston, North Carolina.
Authorities have not said the fires are not linked to the shooting.
The Muslim Anti-Racism Collaborative, the Arab-American Association of New York and Ummah Wide have helped return the churches to their original state with their donations.
According to The Huffington Post the organisations joined together to launch the 'Respond With Love' campaign over the summer, their website stated that: "ALL houses of worship are sanctuaries, a place where all should feel safe."
The fundraiser started off with the aim of raising $10,000, but they hit that target within hours.
Faatimah Knight, a theology student and one of the campaign's organisers said that: "It awakens [in] some and confirms in others that Muslims are diverse and varied and that many of our concerns are domestic concerns.
"Also, Respond with Love is an anti-racism effort and there are many people in this country who are tired of racist rhetoric and racist motivated violence."
