Sahih Bukhari Volume 4, Book 56, Hadith 2911

حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، قَالَ حَدَّثَنِي سِنَانُ بْنُ أَبِي سِنَانٍ الدُّؤَلِيُّ، وَأَبُو سَلَمَةَ بْنُ عَبْدِ الرَّحْمَنِ أَنَّ جَابِرَ بْنَ عَبْدِ اللَّهِ ـ رضى الله عنهما ـ أَخْبَرَ أَنَّهُ، غَزَا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم قِبَلَ نَجْدٍ، فَلَمَّا قَفَلَ رَسُولُ اللَّهِ صلى الله عليه وسلم قَفَلَ مَعَهُ، فَأَدْرَكَتْهُمُ الْقَائِلَةُ فِي وَادٍ كَثِيرِ الْعِضَاهِ، فَنَزَلَ رَسُولُ اللَّهِ صلى الله عليه وسلم وَتَفَرَّقَ النَّاسُ يَسْتَظِلُّونَ بِالشَّجَرِ، فَنَزَلَ رَسُولُ اللَّهِ صلى الله عليه وسلم تَحْتَ سَمُرَةٍ وَعَلَّقَ بِهَا سَيْفَهُ وَنِمْنَا نَوْمَةً، فَإِذَا رَسُولُ اللَّهِ صلى الله عليه وسلم يَدْعُونَا وَإِذَا عِنْدَهُ أَعْرَابِيٌّ فَقَالَ ‏"‏ إِنَّ هَذَا اخْتَرَطَ عَلَىَّ سَيْفِي وَأَنَا نَائِمٌ، فَاسْتَيْقَظْتُ وَهْوَ فِي يَدِهِ صَلْتًا ‏"‏‏.‏ فَقَالَ مَنْ يَمْنَعُكَ مِنِّي فَقُلْتُ ‏"‏ اللَّهُ ‏"‏‏.‏ ثَلاَثًا وَلَمْ يُعَاقِبْهُ وَجَلَسَ‏

Narrated By Jabir bin Abdullah : That he proceeded in the company of Allah's Apostle towards Najd to participate in a Ghazwa. (Holy-battle) When Allah's Apostle returned, he too returned with him. Midday came upon them while they were in a valley having many thorny trees. Allah's Apostle and the people dismounted and dispersed to rest in the shade of the trees. Allah's Apostle rested under a tree and hung his sword on it. We all took a nap and suddenly we heard Allah's Apostle calling us. (We woke up) to see a bedouin with him. The Prophet said, "This bedouin took out my sword while I was sleeping and when I woke up, I found the unsheathed sword in his hand and he challenged me saying, 'Who will save you from me?' I said thrice, 'Allah.' The Prophet did not punish him but sat down.
