Sayyiduna Jundub ibn ‘Abdillah Al Azdi (radiyallahu ‘anhu) reports that Rasulullah (sallallahu ‘alayhi wa sallam) said: “The example of one who teaches people good but forgets about himself is like a lantern which gives light to others while burning itself” (Al Mu’jamul Kabir of Imam Tabarani, Hadith: 1681)
