The ruling on the prayer of one who prays alone behind the rows

Question:
May Allah reward you. Abu Muhammad from Riyadh sent two questions. In the first, he asks: What is the ruling on one who prays alone behind the rows? Is his prayer valid or not?

Answer:
His prayer is not valid because the text has come down regarding this. He saw , and in another hadith, the Prophet (peace and blessings be upon him) said, “There is no prayer for a lone person behind the rows,” and the lone person is the one who prays alone. It is obligatory for one who comes to pray to join the congregation if he finds a place for himself, or to stand to the right of the imam if possible. If neither of these is possible, he should wait until someone comes to pray with him, and he is excused while waiting. Praise be to Allah. Yes.
