The custom of Shiites using their middle finger to swipe their anus after using the toilet, is it only applicable to Shiites or for all the Muslims? Are there any hadithes regarding this?

The custom in reference has no basis in Shari'ah. Shari'ah emphasises on cleaning oneself thoroughly after relieving him/herself. And Allah Ta'ala Knows Best
