Sahih al-Bukhari 1163

The Prophet (ﷺ) did not attach more importance to any Nawafil prayer than the two Rak'ah of prayer before dawn (Fajr) prayer. [Al-Bukhari and Muslim].

وعنها قالت‏:‏ لم يكن النبي، صلى الله عليه وسلم على شيء من النوافل أشد تعاهدًا منه على ركعتي الفجر‏"‏‏.‏ ‏(‏‏(‏متفق عليه‏)‏‏)‏‏.‏

The Prophet (ﷺ) was more particular about offering the two (optional) Rak'at at dawn than he was about offering any of the other optional prayers. [Agreed upon].

وَعَنْهَا قَالَتْ : { لَمْ يَكُنْ اَلنَّبِيُّ ‏- صلى الله عليه وسلم ‏-عَلَى شَيْءٍ مِنْ اَلنَّوَافِلِ أَشَدَّ تَعَاهُدًا مِنْهُ عَلَى رَكْعَتَيْ اَلْفَجْرِ } مُتَّفَقٌ عَلَيْهِ .‏ 1‏ ‏1 ‏- صحيح .‏ رواه البخاري ( 1169 )‏…

‘A’isha said that the Prophet was more particular about observing the two supererogatory rak'as at dawn than about observing any of the other supererogatory prayers. (Bukhari and Muslim.)

وَعَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: لَمْ يَكُنِ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَلَى شَيْءٍ مِنَ النَّوَافِلِ أَشَدَّ تَعَاهُدًا مِنْهُ على رَكْعَتي الْفجْر

The Prophet (may Allah's peace and blessings be upon him) did not observe a voluntary prayer more regularly than the two Rak‘ahs of Fajr

The Prophet (may Allah's peace and blessings be upon him) did not observe a voluntary prayer more regularly than the two Rak‘ahs of Fajr.

لَمْ يَكُنْ عَلَى شَىْءٍ مِنَ النَّوَافِلِ أَشَدَّ مُعَاهَدَةً مِنْهُ عَلَى رَكْعَتَيْنِ قَبْلَ الصُّبْحِ ‏.‏

Narrated by Ā’ishah + 3 other versions Explained

I have never seen the Messenger of Allah (ﷺ) hastening as much in observing supererogatory as two rak'ahs before the (Fard) of the dawn prayer.

مَا رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم فِي شَىْءٍ مِنَ النَّوَافِلِ أَسْرَعَ مِنْهُ إِلَى الرَّكْعَتَيْنِ قَبْلَ الْفَجْرِ ‏.‏
