Mishkat al-Masabih, 1239

Ibn ‘Abbas reported God’s Messenger as saying, “The nobles among my people are those, who know the Qur’an by heart and those who pray during the night.” Baihaqi transmitted it in <i>Shu'ab al-iman</i>.

وَعَنِ ابْنِ عَبَّاسٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «أَشْرَافُ أُمَّتَيْ حَمَلَةُ الْقُرْآنِ وَأَصْحَابُ اللَّيْلِ» . رَوَاهُ الْبَيْهَقِيُّ فِي شُعَبِ الْإِيمَان
