Machine translationRead the Arabic original
Question:
If a person prays alone behind the rows, and another person comes and joins him in the second unit of prayer, is it obligatory for him to be informed after the closing salam that the prayer of the one praying behind him is invalid, and that he must repeat the prayer, or repeat the unit he prayed alone?
Answer:
The Messenger (peace and blessings be upon him) saw a man praying alone behind the rows, so he ordered him to repeat the prayer. If a person says the opening takbir alone behind the rows and bows with the imam, his prayer is not valid. However, if someone comes and joins him before the bowing in the first unit of prayer, his prayer is valid.
