Hadith 180
أَخْبَرَنَا أَخْبَرَنَا يَزِيدُ بْنُ هَارُونَ، حَدَّثَنَا حُمَيْدٌ، عَنْ أَبِي رَجَاءٍ، عَنْ أَبِي الْمُهَلَّبِ، أَنَّ أَبَا مُوسَى رَضِيَ اللهُ عَنْهُ، قَالَ فِي خُطْبَتِهِ: "مَنْ عَلِمَ عِلْمًا، فَلْيُعَلِّمْهُ النَّاسَ، وَإِيَّاهُ أَنْ يَقُولَ مَا لَا عِلْمَ لَهُ بِهِ فَيَمْرُقَ مِنْ الدِّينِ وَيَكُونَ مِنْ الْمُتَكَلِّفِينَ".
It is narrated from Abu al-Muhallab that Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him) said during a sermon: Whoever has knowledge should teach the people, and beware, whoever does not have knowledge about something should not say anything regarding it. If he does so, he will go out of the religion and will be among those who are pretentious.
