I wanted to know whether is it wajib to wear gloves for reciting salat. I mean if I'm wearing full chador then its not enough as i've heard that its important to wear gloves because when we raise our hands for takbir, it is visible

It’s wajib while praying to have the arms covered. The hands up to the wrist can show. So during Takbir if you are careful not to show any part of your arm, then you don’t need to wear any gloves. And remember, you don’t have to raise your hand for Takbir. Just say it without raising your hand if you are concerned that a part of your arm will show if you raise your hand.
