I missed the Fajr rawatib; is it valid for me to pray it immediately after the taslim?

Question:
If I catch up with the imam in the first or second rak'ah of the Fajr prayer, and I have not prayed the Fajr rawatib, is it valid for me to pray it immediately after the taslim?

Answer:
Yes, if you missed the Fajr rawatib before the prayer, you have a choice. If you wish, you may pray it immediately after Fajr, or if you wish, you may delay it until the sun has risen, and that is better. However, if you pray it immediately after Fajr, there is no harm; because the Prophet (peace and blessings be upon him) saw a man praying after Fajr, so he asked him about it, and he said that he had not been able to perform the rawatib before the prayer, so he is now praying it. The Prophet (peace and blessings be upon him) approved of that, and that is because this rawatib is confirmed. The Prophet (peace and blessings be upon him) did not leave this rawatib, neither when present nor when traveling. When he and some of his Companions slept while traveling, and the heat of the sun did not wake them, he (peace and blessings be upon him) did not leave the rawatib; rather, he prayed it first, then he prayed Fajr. Yes.
