Ruling on making up the pre-prayer sunnah after the prayer

Question:
A message was sent by a listener who concealed his name with the letters (A. S). He says: "Whenever I go to the mosque for my Fajr or 'Asr prayer, I find the mu'adhdhin calling the iqamah, or I find that the worshippers have already entered into prayer. In this case, should I pray the sunnah after Fajr and 'Asr? And what about the greeting of the mosque?"

Answer:
If you arrive while the imam is in prayer, or the mu'adhdhin is calling the iqamah, then enter with them into the prayer, and do not pray the greeting of the mosque or the rawatib; because of the saying of the Prophet (peace and blessings be upon him): narrated by Muslim in the Sahih So if you arrive and the mu'adhdhin is calling the iqamah, then line up with them, and say the takbir with them in the prayer, and do not pray the voluntary prayer, neither the sunnah of Fajr nor the greeting. And likewise, if you arrive while they are in prayer, it is even more so that you enter into the prayer, and do not pray the greeting or the rawatib. And when you finish the prayer—the Zuhr—you pray the pre-prayer rawatib, then the post-prayer ones. And Fajr is likewise: when you finish the Fajr prayer, you pray the rawatib sunnah of two rak'ahs after it, or after the sun rises. As for the sunnah of Maghrib, it is after it, and the sunnah of 'Isha' is after it. And praise be to Allah. Yes.
