that the Messenger of Allah ﷺ said: "Whoever calls to guidance, then he receives the reward similar to the reward of whoever follows him, without that diminishing anything from their rewards. And whoever calls to misguidance, then he receives of sin similar to the sins of those who followed him, without that diminishing anything from their sins."
قَالَ رَسُولُ اللَّهِ ﷺ مَنْ دَعَا إِلَى هُدًى كَانَ لَهُ مِنَ الأَجْرِ مِثْلُ أُجُورِ مَنْ يَتَّبِعُهُ لاَ يَنْقُصُ ذَلِكَ مِنْ أُجُورِهِمْ شَيْئًا وَمَنْ دَعَا إِلَى ضَلاَلَةٍ كَانَ عَلَيْهِ مِنَ الإِثْمِ مِثْلُ آثَامِ مَنْ يَتَّبِعُهُ لاَ يَنْقُصُ ذَلِكَ مِنْ آثَامِهِمْ شَيْئًا
