Sahih al-Bukhari, Volume 3, Book 50, Hadith 888 (USC-MSA) ⓘ

Narrated Ubai bin Ka`b: Allah's Messenger said, "Moses the Messenger of Allah," and then he narrated the whole story about him. Al-Khadir said to Moses, "Did not I tell you that you can have no patience with me." (18.72). Moses then violated the agreement for the first time because of forgetfulness, then Moses promised that if he asked Al-Khadir about anything, the latter would have the right to desert him. Moses abided by that condition and on the third occasion he intentionally asked Al-Khadir and caused that condition to be applied. The three occasions referred to above are referred to by the following Verses: "Call me not to account for forgetting And be not hard upon me." (18.73) "Then they met a boy and Khadir killed him." (18.74) "Then they proceeded and found a wall which was on the verge of falling and Khadir set it up straight." (18.77)

حَدَّثَنَا إِبْرَاهِيمُ بْنُ مُوسَى، أَخْبَرَنَا هِشَامٌ، أَنَّ ابْنَ جُرَيْجٍ، أَخْبَرَهُ قَالَ أَخْبَرَنِي يَعْلَى بْنُ مُسْلِمٍ، وَعَمْرُو بْنُ دِينَارٍ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، يَزِيدُ أَحَدُهُمَا عَلَى صَاحِبِهِ وَغَيْرُهُمَا قَدْ سَمِعْتُهُ يُحَدِّثُهُ عَنْ سَعِيدِ بْنِ جُبَيْرٍ قَالَ إِنَّا لَعِنْدَ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ حَدَّثَنِي أُبَىُّ بْنُ كَعْبٍ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ مُوسَى رَسُولُ اللَّهِ ‏"‏ فَذَكَرَ الْحَدِيثَ ‏{‏قَالَ أَلَمْ أَقُلْ إِنَّكَ لَنْ تَسْتَطِيعَ مَعِيَ صَبْرًا‏}‏ كَانَتِ الأُولَى نِسْيَانًا، وَالْوُسْطَى شَرْطًا، وَالثَّالِثَةُ عَمْدًا ‏{‏قَالَ لاَ تُؤَاخِذْنِي بِمَا نَسِيتُ وَلاَ تُرْهِقْنِي مِنْ أَمْرِي عُسْرًا‏}‏‏.‏ ‏{‏لَقِيَا غُلاَمًا فَقَتَلَهُ‏}‏ فَانْطَلَقَا فَوَجَدَا جِدَارًا يُرِيدُ أَنْ يَنْقَضَّ فَأَقَامَهُ‏.‏ قَرَأَهَا ابْنُ عَبَّاسٍ أَمَامَهُمْ مَلِكٌ‏.‏
