عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ مَنْ دَعَا إِلَى هُدًى كَانَ لَهُ مِنَ الْأَجْرِ مِثْلُ أُجُورِ مَنْ يَتَّبِعُهُ لَا يَنْقُصُ ذَلِكَ مِنْ أُجُورِهِمْ شَيْئًا وَمَنْ دَعَا إِلَى ضَلَالَةٍ كَانَ عَلَيْهِ مِنَ الْإِثْمِ مِثْلُ آثَامِ مَنْ يَتَّبِعُهُ لَا يَنْقُصُ ذَلِكَ مِنْ آثَامِهِمْ شَيْئًا
Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Whoever calls towards guidance will have a reward equal to the rewards of those who follow him, without their rewards being diminished in the least. Likewise, whoever calls towards misguidance will bear a sin equal to the sins of those who follow him, without their sins being diminished in the least.
