Al-Nawwās Ibn Sam’ān reported that the Messenger of Allah (ﷺ) ﷺ said “The Qur’an will be brought on the Day of Resurrection, along with its companions who used to act by it, at the front being Sūrah al-Baqarah and Al ‘Imran. He (the Messenger ﷺ) likened them (the two suwar) to three things which I did not forget. He said they will be like two clouds, or two black canopies with light between them, or like two flocks of birds in ranks pleading for one who recited them. Reference: Sahih Muslim 805

عَنْ جُبَيْرِ بْنِ نُفَيْرٍ، قَالَ سَمِعْتُ النَّوَّاسَ، بْنَ سَمْعَانَ الْكِلاَبِيَّ يَقُولُ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقُولُ " يُؤْتَى بِالْقُرْآنِ يَوْمَ الْقِيَامَةِ وَأَهْلِهِ الَّذِينَ كَانُوا يَعْمَلُونَ بِهِ تَقْدُمُهُ سُورَةُ الْبَقَرَةِ وَآلُ عِمْرَانَ " . وَضَرَبَ لَهُمَا رَسُولُ اللَّهِ صلى الله عليه وسلم ثَلاَثَةَ أَمْثَالٍ مَا نَسِيتُهُنَّ بَعْدُ قَالَ " كَأَنَّهُمَا غَمَامَتَانِ أَوْ ظُلَّتَانِ سَوْدَاوَانِ بَيْنَهُمَا شَرْقٌ أَوْ كَأَنَّهُمَا حِزْقَانِ مِنْ طَيْرٍ صَوَافَّ تُحَاجَّانِ عَنْ صَاحِبِهِمَا.
