Status: False
This claim was first made by the vitriolic polemicist Ann Coulter.
This claim was repeated without attribution on the Christian Broadcasting Network (CBN), a Pat Robertson channel, during a plug for counterjihadi Robert Spencer's book 'Religion of Peace'.
Response
"the threat from Islamic terrorism is much more minimal than commonly assumed; in the U.S., it accounts for 6% of terrorist attacks, and in Europe not even half of a percent"
United States
"I used official FBI records to show that only 6% of terrorist attacks on U.S. soil from 1980 to 2005 were carried out by Islamic extremists. The remaining 94% were from other groups (42% from Latinos, 24% from extreme left wing groups, 7% from extremist Jews, 5% from communists, and 16% from all other groups)."
Europe
"The results are stark, and prove decisively that not all terrorists are Muslims. In fact, a whopping 99.6% of terrorist attacks in Europe were by non-Muslim groups; a good 84.8% of attacks were from separatist groups completely unrelated to Islam. Leftist groups accounted for over sixteen times as much terrorism as radical Islamic groups. Only a measly 0.4% of terrorist attacks from 2007 to 2009 could be attributed to extremist Muslims."
