[Machine] A man came to the Prophet Muhammad ﷺ and asked, "O Messenger of Allah, which cities are the worst?" The Prophet replied, "I do not know." When Gabriel (the angel) came to him, he said, "O Gabriel, which cities are the worst?" Gabriel replied, "I do not know until I ask my Lord." Then Gabriel left and stayed as long as Allah willed, then he returned and said, "O Muhammad, you asked me which cities are the worst? And I said, 'I do not know' and I asked my Lord. He replied, 'The worst of them are the markets.'" This hadith has been transmitted by all narrators, except Abdullah bin Muhammad bin Aqil. Al-Bukhari has unique narration with Abu Hudhaifah as the witness. This hadith is the origin for the saying of the scholar, "I do not know," and it has a witness from Abdullah bin Muhammad bin Aqil. Al-Dhahabi did not mention it in his summary.
أَنَّ رَجُلًا أَتَى النَّبِيَّ ﷺ فَقَالَ يَا رَسُولَ اللَّهِ أَيُّ الْبِلَادِ شَرٌّ؟ فَقَالَ «لَا أَدْرِي» فَلَمَّا أَتَاهُ جِبْرِيلُ قَالَ «يَا جِبْرِيلُ أَيُّ الْبُلْدَانِ شَرٌّ؟» قَالَ لَا أَدْرِي حَتَّى أَسْأَلَ رَبِّي فَانْطَلَقَ جِبْرِيلُ فَمَكَثَ مَا شَاءَ اللَّهُ أَنْ يَمْكُثَ ثُمَّ جَاءَ فَقَالَ يَا مُحَمَّدُ إِنَّكَ سَأَلْتَنِي أَيُّ الْبِلَادِ شَرٌّ؟ وَإِنِّي قُلْتُ لَا أَدْرِي وَإِنِّي سَأَلْتُ رَبِّي فَقُلْتُ أَيُّ الْبِلَادِ شَرٌّ فَقَالَ «أَسْوَاقُهَا» قَدِ احْتَجَّا جَمِيعًا بِرُوَاةِ هَذَا الْحَدِيثِ إِلَّا عَبْدَ اللَّهِ بْنَ مُحَمَّدِ بْنِ عَقِيلٍ وَقَدْ تَفَرَّدَ الْبُخَارِيُّ بِالِاحْتِجَاجِ بِأَبِي حُذَيْفَةَ وَهَذَا الْحَدِيثُ أَصْلٌ فِي قَوْلِ الْعَالِمِ لَا أَدْرِي وَلَهُ شَاهِدٌ عَنْ عَبْدِ اللَّهِ بْنِ مُحَمَّدِ بْنِ عَقِيلٍ سكت عنه الذهبي في التلخيص
