Mu’adh on Conscience: Beware one contradicting your conscience

Abu Idris reported: Mu’adh ibn Jabal, may Allah be pleased with him, said, “I warn you of the deviation of the wise man, for Satan can speak a word of misguidance through the wise man and the hypocrite can speak the truth. Thus, accept the truth for upon the truth is light.” They said, “How can we know if the wise man, may Allah have mercy on him, has spoken misguidance?” Mu’adh said, “It is a word you reject from him and you say: What is this? Yet do not turn away from him, for he may retract it and return to some of what you recognize. Verily, the place of faith and deeds is set until the Day of Resurrection, so whoever seeks them will find them.”

عن أبي إدريس أَنَّ مُعَاذَ بْنَ جَبَلٍ رَضِيَ اللَّهُ تَعَالَى عَنْهُ قَالَ وَأُحَذِّرُكُمْ زَيْغَةَ الْحَكِيمِ فَإِنَّ الشَّيْطَانَ يَقُولُ فِي الْحَكِيمِ كَلِمَةَ الضَّلالَةِ وَقَدْ يَقُولُ الْمُنَافِقُ كَلِمَةَ الْحَقِّ فَاقْبَلُوا الْحَقَّ فَإِنَّ عَلَى الْحَقِّ نُورًا فَقَالُوا وَمَا يُدْرِينَا رَحِمَكَ اللَّهُ أَنَّ الْحَكِيمَ قَدْ يَقُولُ كَلِمَةَ الضَّلالَةِ قَالَ هِيَ كَلِمَةٌ تُنْكِرُونَهَا مِنْهُ وَتَقُولُونَ مَا هَذِهِ فَلا يُثْنِيكُمْ فَإِنَّهُ يُوشِكُ أَنْ يَفِئَ وَيُرَاجِعَ بَعْضَ مَا تَعْرِفُونَ وَإِنَّ الْعَمَلَ وَالإِيمَانَ مَكَانَهُمَا إِلَى يَوْمِ الْقِيَامَةِ مَنِ ابْتَغَاهُمَا وَجَدَهُمَا
