[Wearing two rings]

The answer: In the marginalia of Sharḥ al-Azhār according to the madhhab: It is not permissible to combine between two rings on one hand. And in it: As for a ring on each hand, then that likewise is not permissible.
I say: Perhaps the evidence for that is what there is in such combining of resemblance to women. And Allah knows best.
