Abu Umama said he heard Allah's Messenger (ﷺ) say:Recite the Qur'an, for on the Day of Resurrection it will come as an intercessor for those who recite It. Recite the two bright ones, al-Baqara and Surah Al 'Imran, for on the Day of Resurrection they will come as two clouds or two shades, or two flocks of birds in ranks, pleading for those who recite them. Recite Surah al-Baqara, for to take recourse to it is a blessing and to give it up is a cause of grief, and the magicians cannot confront it. (Mu'awiya said: It has been conveyed to me that here Batala means magicians.)
حَدَّثَنِي الْحَسَنُ بْنُ عَلِيٍّ الْحُلْوَانِيُّ، حَدَّثَنَا أَبُو تَوْبَةَ، - وَهُوَ الرَّبِيعُ بْنُ نَافِعٍ - حَدَّثَنَا مُعَاوِيَةُ، - يَعْنِي ابْنَ سَلاَّمٍ - عَنْ زَيْدٍ، أَنَّهُ سَمِعَ أَبَا سَلاَّمٍ، يَقُولُ حَدَّثَنِي أَبُو أُمَامَةَ، الْبَاهِلِيُّ قَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " اقْرَءُوا الْقُرْآنَ فَإِنَّهُ يَأْتِي يَوْمَ الْقِيَامَةِ شَفِيعًا لأَصْحَابِهِ اقْرَءُوا الزَّهْرَاوَيْنِ الْبَقَرَةَ وَسُورَةَ آلِ عِمْرَانَ فَإِنَّهُمَا تَأْتِيَانِ يَوْمَ الْقِيَامَةِ كَأَنَّهُمَا غَمَامَتَانِ أَوْ كَأَنَّهُمَا غَيَايَتَانِ أَوْ كَأَنَّهُمَا فِرْقَانِ مِنْ طَيْرٍ صَوَافَّ تُحَاجَّانِ عَنْ أَصْحَابِهِمَا اقْرَءُوا سُورَةَ الْبَقَرَةِ فَإِنَّ أَخْذَهَا بَرَكَةٌ وَتَرْكَهَا حَسْرَةٌ وَلاَ تَسْتَطِيعُهَا الْبَطَلَةُ " . قَالَ مُعَاوِيَةُ بَلَغَنِي أَنَّ الْبَطَلَةَ السَّحَرَةُ .
