Praying Qada's Sallah instead of other person

Worshiping God especially Sallah is an important issue and Qada of Sallah is one of these issues. Most of scholars believe that any person who unable to perform one's prayer (Sallah) within the prescribed time, the prayer must be performed the Qada of Sallah. But a number of Foghaha believe that there is no need for Qada if the Sallah of a person become Qada inadvertently. Furthermore, Praying Qada of Sallah instead of other person is one of subsets of the issue of Qada. Despite of all various ideas in this subject, but Foghaha are certain that Sallah of Qada is not allowed for alive person. Because the philosophy of Sallah is stooping for God, and in this case the purpose wouldn’t occur. Therefore most of Foghaha claim that Sallah of Qada for dead person is not allowed as well. But we could pray for him/her and send the divine reward (Savab) of the Sallah for the soul of the dead person. All these issues would discuss in this Article thoroughly.
