Emphasis on Performing two Rak'ah Sunnah before Dawn (Fajr) Prayer
وَعَنْهَا قَالَتْ: لَمْ يَكُنْ اَلنَّبِيُّ، صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ عَلَى شَيْءٍ مِنْ اَلنَّوَافِلِ أَشَدَّ تَعَاهُدًا مِنْهُ عَلَى رَكْعَتَيْ اَلْفَجْرِ". ((مُتَّفَقٌ عَلَيْهِ)).
'Aishah (May Allah be pleased with her) reported: 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].
