If the first row in the mosque is full, does one wait for another person to arrive, or does one stand to the right of the imam?

Question:
Honorable Shaykh, may Allah grant you success. He says: If a person arrives for the congregational prayer and the first row is full, is it obligatory for him to wait until another person arrives, or does he stand to the right of the imam?

Answer:
If that happens, he stands to the right of the imam. Yes, he stands to the right of the imam, because he has to have another person with him. If that does not happen, he waits until someone comes to pray with him. Yes.
