Best of people are most useful
خَيْرُ النَّاسِ أَنْفَعُهُمْ لِلنَّاسِ
Khayru-n-nasi anfa'uhum li-n-nas.
"The best of people are those most beneficial to people."
Narrated by Jabir ibn Abdullah. Mu'jam al-Awsat 5937 (hasan according to al-Albani)
A short reflection
A measure that cuts through ranks. Not the most learned, not the most pious in private, not the most known. The one whose hand others actually use.
