The ruling on praying the Fajr Sunnah after the iqamah has been called

The question: May Allah reward you. He also says: There are some people who enter the mosque when the prayer has already been established, but they know from the imam that he prolongs the first rak'ah, so they pray the two rak'ahs of Fajr before joining the imam?
The answer: This is not permissible. Some people do this; some of our brothers from Pakistan, India, and others do it. This is an error. Even if some scholars have said it, it is an error that contradicts the Sunnah. The Sunnah for the ma'mum, if he enters and the imam has already entered the prayer, is to line up and not pray the Fajr rawatib or any other voluntary prayer, but rather to line up with the imam. This is based on what was established from him (peace and blessings be upon him) that he said: Al-Imam Muslim narrated it in his Sahih.
Therefore, it is obligatory for the one who enters when the imam has established the prayer to pray with the imam and postpone the Sunnah until after the prayer or after the sun rises. As for praying it while the imam is praying, this is not permissible due to the aforementioned hadith, which is his (peace and blessings be upon him) saying: Muslim narrated it in his Sahih. And in a narration by Ahmad: Therefore, it is obligatory for the one who enters when the imam has said the takbir for the prayer or when the iqamah has been called to hasten and line up with the people. The nafilah, praise be to Allah, is broad in its ruling; if you pray it after the prayer or after the sun rises, or if you leave it, it is a nafilah. However, the best is to pray it after the prayer or after the sun has risen, because it is a regular Sunnah with great reward. Yes.
