The ruling on one who prays a single rak'ah alone behind the row and then another person joins him
Machine translationRead the Arabic original
Question:
Honorable Shaykh, may Allah grant you success. He says: If a man begins the prayer alone behind the row, and prays one or two rak'ahs alone, and then another man comes and stands with him,
Answer:
No, that is not sufficient. His prayer is not valid unless another person joins his row before he bows. If he joins his row before he bows, his state of being alone is removed. But if he bows alone and no one comes, his prayer is not valid. Yes.
