Is it permissible to wear ring on pinky finger or ring finger on both hands?I read that is recommended to wear ring in one hand (left) if less than 4 ring is it correct?
Is it wrong or recommended to wear like that?

The recommendation is satisfied by wearing one ring in the right hand, in either pinky or victory fingers.
Wearing four rings, two in each hand is beyond the recommendation, and it is up to you.
