The ruling on a latecomer joining the prayer during the final tashahhud

Question:
If he enters while the imam is in the final tashahhud, does he wait until the imam says the taslim and then pray with him, or does he join him?

Answer:
May Allah reward you for that. This is based on the generality of the saying of the Messenger (peace and blessings be upon him): "Pray what you catch up with, and make up what you missed," and they agreed upon it. He is considered to have the reward of the congregation. It was said that the Prophet (peace and blessings be upon him) and the congregation... [garbled text]... The Prophet (peace and blessings be upon him) said: We know that there are people who perform wudu' and they will catch up with it. He does not enter with the people as the Muslim measured. He does not fast with the people; if they fast for three days, he fasts with them; if they fast for three hours and twenty minutes, if they break their fast, he breaks his fast with them, and if they fast, he fasts with them, just as it was said: "Fasting is the day the people fast, and breaking the fast is the day the people break their fast." He does not lag behind the people. It is not permissible for him to advance or delay with the Muslims. Breaking the fast is the day the people break their fast, and fasting is the day the people fast.
