عَنْ أَبِي مَسْعُودٍ الْأَنْصَارِيِّ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ مَنْ دَلَّ عَلَى خَيْرٍ فَلَهُ مِثْلُ أَجْرِ فَاعِلِهِ
1893 صحيح مسلم

Abu Mas'ud reported: The Prophet, peace and blessing be upon him said, " Whoever guides someone to goodness will have a reward like the one who did it."

(Sahih Muslim).
