Compiled by Imam Muhammad al-Bukhari
حَدَّثَنَا مُنْذِرُ بْنُ الْوَلِيدِ بْنِ عَبْدِ الرَّحْمَنِ الْجَارُودِيُّ، حَدَّثَنَا أَبِي، حَدَّثَنَا شُعْبَةُ، عَنْ مُوسَى بْنِ أَنَسٍ، عَنْ أَنَسٍ ـ رضى الله عنه ـ قَالَ خَطَبَ رَسُولُ اللَّهِ صلى الله عليه وسلم خُطْبَةً مَا سَمِعْتُ مِثْلَهَا قَطُّ، قَالَ " لَوْ تَعْلَمُونَ مَا أَعْلَمُ لَضَحِكْتُمْ قَلِيلاً وَلَبَكَيْتُمْ كَثِيرًا ". قَالَ فَغَطَّى أَصْحَابُ رَسُولِ اللَّهِ صلى الله عليه وسلم وُجُوهَهُمْ لَهُمْ خَنِينٌ، فَقَالَ رَجُلٌ مَنْ أَبِي قَالَ فُلاَنٌ فَنَزَلَتْ هَذِهِ الآيَةُ {لاَ تَسْأَلُوا عَنْ أَشْيَاءَ إِنْ تُبْدَ لَكُمْ تَسُؤْكُمْ}. رَوَاهُ النَّضْرُ وَرَوْحُ بْنُ عُبَادَةَ عَنْ شُعْبَةَ.
The Prophet (ﷺ) delivered a sermon the like of which I had never heard before. He said, "If you but knew what I know then you would have laughed little and wept much." On hearing that, the companions of the Prophet (ﷺ) covered their faces and the sound of their weeping was heard. A man said, "Who is my father?" The Prophet (ﷺ) said, "So-and-so." So this Verse was revealed: "Ask not about things which, if made plain to you, may cause you trouble." (5.101)
