Is saying, "Religion is ease, and if religion is not ease... then what my family is doing is correct, because they say I am experiencing intrusive thoughts (waswasa)," considered an act of disbelief (kufr)?

A small amount of blood is excused, whether it is on clothes or bedding. A Muslim does not become an infidel because of the thoughts that come to him or the words that issue from him. One must beware of whisperings (waswas) and not succumb to them.
