What is the ruling on praying on Friday during the khutbah?

Question:
On Friday, while the khatib is delivering the khutbah, it is observed that some people are praying. The Messenger of Allah (peace and blessings be upon him) said: There is no prayer and no speech. So what is your guidance? May Allah reward you with good.

Answer:
No, the Prophet (peace and blessings be upon him) did not say "there is no prayer"; rather, he prohibited speech. As for the one who enters while the khutbah is being delivered, he prays two light rak'ahs before sitting down, then sits to listen to the khutbah. This is because the Prophet (peace and blessings be upon him) ordered a man who had entered and sat down to stand up and pray two rak'ahs. So, if one enters while the imam is delivering the khutbah, he does not sit until he has prayed two light rak'ahs. However, if he has already prayed the greeting of the mosque and sat down, and then the imam enters, he does not stand up for a voluntary prayer; he does not stand up for a voluntary prayer, but rather listens to the imam. Once the imam enters, the time for the voluntary prayer ends. If the imam exits, meaning he begins the khutbah, the time for the voluntary prayer ends. As for the one who arrives early before the imam enters, he may pray as much of the voluntary prayers as he wishes, the minimum of which is the greeting of the mosque, and then he sits.
