If One Does Not Benefit from Praying Alone

Question : Now, some scholars made an exception in the case where one prays alone for a valid excuse. What is that exception? It is when one does not benefit from it.

Answer : Correct. If one does not benefit at all from praying alone, then he does not pray alone, provided that the imam hastens in his prayer to the extent that is obligatory. If we assume that the follower prays alone in order to hasten even more, his hastening would compromise the obligatory requirements. This exception is correct.
