Performing Umrah on Behalf of The Deceased

I made the intention to perform the Umrah for my eldest brother since he has passed away, so I want to know, is this act from the religious acts which whose reward will reach the deceased?

Yes, because this is something good, that being you performing the Umrah on behalf of your deceased brother whether it be the obligatory Umrah or the recommended voluntary Umrah - so this is a great act.

However, the permissibility of this is based upon the condition that you have already performed the obligatory Umrah for yourself first, and Allah is the Most Knowledgeable.
