If one finds the row complete and cannot enter it

Question:
The Honorable Shaykh, may Allah grant you success. If a man comes to the mosque and finds that the row is complete and he cannot enter the row, what should he do?

Answer:
He should wait if someone comes to pray with him; otherwise, he should wait and not pray alone behind the row, because the Prophet (peace and blessings be upon him) prohibited that and ordered the one who prays behind the row to repeat the prayer, and he said . Wait, if someone comes to pray with him. Praise be to Allah, no one came, that is known. Wait, and no one came, that is known. Pray alone. When the imam finishes the prayer, pray alone; it is required of him. Yes.
