That he was in the company of Messenger of Allah ﷺ on some of his journeys. (The sub-narrator ʿAbdullah adds, "I think that Abu Bashir also said, 'And the people were at their sleeping places.") Allah's Apostle sent a messenger ordering: "There shall not remain any necklace of string or any other kind of necklace round the necks of camels except it is cut off."  

بَشِيرٍ الأَنْصَارِيّ َ ؓ أَخْبَرَهُ أَنَّهُ كَانَ مَعَ رَسُولِ اللَّهِ ﷺ فِي بَعْضِ أَسْفَارِهِ قَالَ عَبْدُ اللَّهِ حَسِبْتُ أَنَّهُ قَالَ وَالنَّاسُ فِي مَبِيتِهِمْ فَأَرْسَلَ رَسُولُ اللَّهِ ﷺ رَسُولاً أَنْ لاَ يَبْقَيَنَّ فِي رَقَبَةِ بَعِيرٍ قِلاَدَةٌ مِنْ وَتَرٍ أَوْ قِلاَدَةٌ إِلاَّ قُطِعَتْ  

"لا يَبْقَيَنَّ فِي رَقَبَةِ بَعِيرٍ قِلادَةٌ مِنْ وَتَرٍ إِلا قُطِعَتْ".
