Mishkat al-Masabih 1201
‘Abdallah b. ‘Amr b. al-‘As reported God’s Messenger as saying, “If anyone makes proper use of ten verses he will not be recorded among the negligent; if anyone makes proper use of a hundred verses he will be recorded among those who are obedient to God:
and if anyone makes proper use of a thousand verses he will be recorded among those who receive huge rewards.” 

Abu Dawud transmitted it.
وَعَنْ عَبْدِ اللَّهِ بْنِ عَمْرِو بْنِ الْعَاصِ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ قَامَ بِعَشْرِ آيَاتٍ لَمْ يُكْتَبْ مِنَ الْغَافِلِينَ وَمَنْ قَامَ بِمِائَةِ آيَةٍ كُتِبَ مِنَ الْقَانِتِينَ وَمَنْ قَامَ بِأَلْفِ آيَةٍ كُتِبَ من المقنطرين» . رَوَاهُ أَبُو دَاوُد
