Q. Can we wear a ring on the first finger of our right or left hand?
A. Yes, it is permissible to wear a ring on the first finger. It is also allowed to wear it on the right and or on the left hand, although the right hand is better, since the prophet (SAS) used to wear a ring on his right hand sometimes, and on his left hands sometimes.
And Allah knows best.
