The individual praying behind the rows
Machine translationRead the Arabic original
Question:
This questioner says: Shaykh, if a person praying alone prays behind the rows, and then someone comes and joins him in the second rak'ah, if I inform him after the taslim that it is not valid for an individual to pray behind the rows, does he repeat the prayer, or does he repeat the rak'ah he prayed alone behind the rows?
Answer:
If he bowed in a rak'ah before anyone came to join him, his prayer is not valid, because the Prophet (peace and blessings be upon him) said, "There is no prayer for a single person behind the rows," and it is not permissible for anyone to pray opposite him, because his prayer is not valid. Yes.
