The Prophet said: "Whoever teaches some knowledge will have the reward of the one who acts upon it, without that detracting from his reward in the slightest."
أَنَّ النَّبِيَّ ﷺ قَالَ مَنْ عَلَّمَ عِلْمًا فَلَهُ أَجْرُ مَنْ عَمِلَ بِهِ لاَ يَنْقُصُ مِنْ أَجْرِ الْعَامِلِ
[Machine] The Messenger of Allah ﷺ said: "Whoever teaches knowledge, he will have the reward of what the person who acts upon it earns, without any decrease in the reward of the person who acts."
قَالَ رَسُولُ اللهِ ﷺ «مَنْ عَلَّمَ عِلْمًا فَلَهُ أَجْرٌ مَا عَمِلَ بِهِ عَامَلٌ وَلَا يَنْقُصُ مِنْ أَجْرِ الْعَامِلِ»
"مَنْ عَلَّمَ عِلمًا فَلَهُ أَجْرُ مَنْ عَمِلَ بهِ، لا يَنْقُصُ مِنْ أَجْر الْعَامِل شَيئًا".
