Whether to offer the two supererogatory Rak`ahs before Fajr or the two obligatory Rak`ahs of Fajr Prayer in case of waking up after sunrise

Q 5: If one wakes up after sunrise, must one offer first the Sunnah (supererogatory) Salah of the Fajr (Dawn) Prayer or the Fajr Prayer itself? A: If a Muslim oversleeps or forgets the Fajr Prayer until sunrise, it is permissible to offer its Sunnah first. If one cannot, like one who has joined the congregation; then it should be offered after the obligatory Salah (prayer). It is related by Abu Dawud in his Sunan (Hadith compilation classified by jurisprudential themes) on the authority of Qays ibn `Umar that "The Messenger of Allah (peace be upon him) saw a person offering two Rak`ahs (units of Prayer) after the Fajr Prayer was over. He (peace be upon him) said, 'Fajr Prayer is two Rak`ahs only.' The man replied, 'I did not offer the two Rak`ahs before it, so I have offered them now.' The Messenger of Allah (peace be upon him) kept silent." This indicates that if one cannot offer the Sunnah of the Fajr Prayer before it, it may be offered after it or (Part No. 6; Page No. 125

When the Prophet (peace be upon him) and his Sahabah (Companions) fell asleep while traveling and woke up after sunrise due to the heat, they pronounced the Adhan (call to Prayer) and the Iqamah (call to start the Prayer) for the Fajr Prayer and offered its Sunnah before it.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
