حَدَّثَنَا أَبُو الْمُغِيرَةِ حَدَّثَنَا عَبْدَةُ عَنْ خَالِدِ بْنِ مَعْدَانَ قَالَ سُورَةُ الْبَقَرَةِ تَعْلِيمُهَا بَرَكَةٌ وَتَرْكُهَا حَسْرَةٌ وَلَا يَسْتَطِيعُهَا الْبَطَلَةُ وَهِيَ فُسْطَاطُ الْقُرْآنِ

Narrated to us [Abu Al Mughirah] Narrated to us [Abdah] from [Khalid bin Ma'And] he said:Teaching Surah Al Baqarah is a blessing and leaving it is a loss. Even wizards wouldn't be able to deal with it. He is the perfecter of the Qur'an.
