Arabic hadith text
حَدَّثَنِي مَالِكٌ، عَنْ إِسْحَاقَ بْنِ عَبْدِ اللَّهِ بْنِ أَبِي طَلْحَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ سَمِعْتُ عُمَرَ بْنَ الْخَطَّابِ، وَخَرَجْتُ، مَعَهُ حَتَّى دَخَلَ حَائِطًا فَسَمِعْتُهُ وَهُوَ، يَقُولُ وَبَيْنِي وَبَيْنَهُ جِدَارٌ - وَهُوَ فِي جَوْفِ الْحَائِطِ - عُمَرُ بْنُ الْخَطَّابِ أَمِيرُ الْمُؤْمِنِينَ بَخٍ بَخٍ وَاللَّهِ لَتَتَّقِيَنَّ اللَّهَ أَوْ لَيُعَذِّبَنَّكَ ‏.‏
