Mishkat al-Masabih 2 Knowledge كتاب العلم 40

وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «تَعَلَّمُوا الْفَرَائِضَ وَالْقُرْآنَ وَعَلِّمُوا النَّاسَ فَإِنِّي مَقْبُوضٌ» . رَوَاهُ التِّرْمِذِيّ

Abu Huraira reported God’s messenger as saying, “Learn the things which are made obligatory and the Qur’an, and teach them to people, for I shall die.” Tirmidhi transmitted it.
