Mishkat al-Masabih 4571
'Abdallah b. Mas'ud reported God’s messenger as saying:
“Make use of the two remedies: honey and the Qur’an.” 

Ibn Majah and Baihaqi, in Shu'ab al-lman, transmitted the two traditions, Baihaqi saying the correct view is that the second goes no farther back than Ibn Mas'ud.
وَعَنْ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: 
" عَلَيْكُمْ بِالشِّفَاءَيْنِ: الْعَسَلِ وَالْقُرْآنِ ". رَوَاهُمَا ابْنُ مَاجَهْ وَالْبَيْهَقِيُّ فِي شُعَبِ الْإِيمَانِ وَقَالَ: وَالصَّحِيحُ أَنَّ الْأَخِيرَ مَوْقُوفٌ عَلَى ابْنِ مَسْعُودٍ
