The ruling on establishing a second congregation in the mosque

Question:
Honorable Shaykh, may Allah grant you success. He says: Is it permissible to establish a second congregation in the mosque? Or is it better that I return to my home and pray with my family?

Answer:
If the first congregation has passed, a second congregation is established. However, if the first congregation has not finished, it is not permissible to establish a second one. Nor is it permissible for you to come in while the imam is praying and say, "By Allah, we are not praying with him," and then sit down until he finishes the taslim. This is not permissible for you. It is not permissible for the Muslims to divide or to be separated. But if the first congregation has passed, there is no harm; rather, it is recommended that you establish a second prayer.
A man entered while the Prophet (peace and blessings be upon him) had finished the prayer, so the Prophet (peace and blessings be upon him) said: ? This indicates that establishing a congregation after the first one has passed is commanded and prescribed. Do not return to your homes; pray in the mosque, and you are excused. Yes.
