Imam Khamenei: US and UK foster divide by their mercenaries operating as muslims among shias& sunnis

Shias scholars’ arguments about their faith are indeed sweeping; but it would not provide them with the license to vilify and vituperate their rival scholars in Shia world, and vice versa.
We do know that [some] spend huge amounts of money to have books of slander and vilification written in the name of #Sunnis to target #Shias; and to have books of vilification written in the name of Shias to target Sunnis. The same source pays the money to have these books printed. Are not these symptoms warning? Both Shias and Sunnis should understand this.
