[That they may bear their own burdens], meaning: their sins, [in full on the Day of Resurrection], referring to those who said: 'Legends of the ancients,' [and some of the burdens of those whom they misguide without knowledge. Unquestionably, evil is that which they bear], meaning: how wretched is that which they carry.
Yahya [narrated] from Abu al-Ashhab, from al-Hasan, who said: The Messenger of Allah (ﷺ) said:
'Whoever calls to guidance and is followed in it, he shall have a reward equivalent to those who followed him, without that diminishing anything of their rewards. And whoever calls to misguidance and is followed in it, he shall bear a burden of sin equivalent to those who followed him, without that diminishing anything of their burdens.'
Surat an-Nahl from verse (26) to verse (29).
﴿ليحملوا أوزارهم﴾ أَيْ: آثَامَهُمْ ﴿كَامِلَةً يَوْمَ الْقِيَامَةِ﴾ يَعْنِي الَّذِينَ قَالُوا: أَسَاطِيرُ الأَوَّلِينَ (ل ١٧٣) ﴿وَمِنْ أَوْزَارِ الَّذِينَ يُضِلُّونَهُمْ بِغَيْرِ عِلْمٍ أَلا سَاءَ مَا يَزِرُونَ﴾ أَيْ: بِئْسَ مَا يَحْمِلُونَ.
يحيى: عَنْ أَبِي الأَشْهَبِ، عَنِ الحَسَنِ قَالَ: قَالَ رَسُولُ اللَّهِ ﷺ:
أَيُّمَا داعٍ دَعَا إِلَى هُدًى فَاتُّبِعَ عَلَيْهِ، فَلَهُ مِثْلُ أَجْرِ مَنِ اتَّبَعَهُ، وَلا يَنْقُصُ ذَلِكَ مِنْ أُجُورِهِمْ شَيْئًا، وَأَيُّمَا داعٍ دَعَا إِلَى ضلالةٍ فَاتُّبِعَ عَلَيْهَا فَعَلَيْهِ مِثْلُ وِزْرِ مَنِ اتَّبَعَهُ، لَا يَنْقُصُ ذَلِك من أوزارهم شَيْئا ".
