Narrated Abu Umamete, [may Allah be pleased with him]
That the Prophet [sallallaahu alayhi wa sallam] said:


"Verily Allah, the Exalted, His angels and the inhabitants of heaven and earth, that even ants in her den, pray for those who teach people good jobs."


(Termidhu 2685 and Sheikh Albani said that the hadith is Sahih, see: Sahih-Targheeb 1/36 and Sahih Al-Jami 1883.)
