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

Question:
This Shaykh is asking about the prayer on the Day of Resurrection, where he enters the row alone.

Answer:
It is not permissible for a person praying alone to pray behind the row. The Prophet (peace and blessings be upon him) said , and he saw a man praying behind the row, so he ordered him to repeat the prayer. Either he enters the row, or he waits until someone comes to form a row with him. Yes, and Allah knows best, and may Allah send prayers and peace upon our Prophet Muhammad, and upon his family and all his Companions.
