That he fought in a Ghazwa towards Najd along with Messenger of Allah ﷺ and when Messenger of Allah ﷺ returned, he too, returned along with him. The time of the afternoon nap overtook them when they were in a valley full of thorny trees. Messenger of Allah ﷺ dismounted and the people dispersed amongst the thorny trees, seeking the shade of the trees. Messenger of Allah ﷺ took shelter under a Samura tree and hung his sword on it. We slept for a while when Messenger of Allah ﷺ suddenly called us, and we went to him, to find a bedouin sitting with him. Messenger of Allah ﷺ said, "This (bedouin) took my sword out of its sheath while I was asleep. When I woke up, the naked sword was in his hand and he said to me, 'Who can save you from me?, I replied, 'Allah.' Now here he is sitting." Messenger of Allah ﷺ did not punish him (for that). (Using translation from Bukhārī 4135)   

أَنَّهُ غَزَا مَعَ رَسُولِ اللهِ ﷺ غَزْوَةً قِبَلَ نَجْدٍ فَلَمَّا قَفَلَ النَّبِيُّ ﷺ قَفَلَ مَعَهُ وَأَدْرَكَتْهُمُ الْقَائِلَةُ يَوْمًا يَعْنِي فِي وَادٍ كَثِيرِ الْعِضَاهِ فَنَزَلَ النَّبِيُّ ﷺ وَتَفَرَّقَ النَّاسُ فِي الْعِضَاهِ يَسْتَظِلُّونَ بِالشَّجَرِ وَنَزَلَ النَّبِيُّ ﷺ تَحْتَ ظِلِّ شَجَرَةٍ فَعَلَّقَ بِهَا سَيْفَهُ قَالَ جَابِرٌ فَنِمْنَا نَوْمَةً ثُمَّ إِذَا النَّبِيُّ ﷺ يَدْعُونَا فَأَجَبْنَاهُ فَإِذَا عِنْدَهُ أَعْرَابِيٌّ جَالِسٌ فَقَالَ رَسُولُ اللهِ ﷺ «إِنَّ هَذَا اخْتَرَطَ سَيْفِي وَأَنَا نَائِمٌ فَاسْتَيْقَظْتُ وَهُوَ فِي يَدِهِ صَلْتًا» فَقَالَ مَنْ يَمْنَعُكَ مِنِّي؟ فَقُلْتُ «اللهُ» فَقَالَ مَنْ يَمْنَعُكَ مِنِّي؟ فَقُلْتُ «اللهُ» فَقَالَ مَنْ يَمْنَعُكَ مِنِّي؟ فَقُلْتُ «اللهُ فَشَامَ السَّيْفَ وَجَلَسَ وَلَمْ يُعَاقِبْهُ النَّبِيُّ ﷺ وَقَدْ فَعَلَ ذَلِكَ»
