Prayer: When praying on behalf of someone, must all parts be recited, the order kept, and the deceased named?

English:

Question #706:

Someone is hired to perform prayer on another’s behalf, how is he to go about it?

i. Is it obligatory for him to recite the adhān, the iqāmah, the threefold salāms, and the complete tasbīḥāt al-arba‘ah?

ii. If he performs the noon and afternoon prayers, for example, one day and performs the complete five daily prayers on the next day, will it be necessary to observe their order?

iii. Is it necessary to mention the specifics of the deceased person for the prayer performed on their behalf?

Answer #706:

Mentioning the specifics of the deceased person is not necessary. Order should be observed only between noon and afternoon and between maghrib and ‘ishā’ prayers of the same day. If, in the hiring contract, the person hired to perform the prayers is not ordered to follow a particular method, he is just required to perform the obligatory parts of the prayers.
