That they were in the company of Messenger of Allah ﷺ on the day of Al-Hudaibiya and their number was 1400 or more. They camped at a well and drew its water till it was dried. When they informed Allah's Apostle of that, he came and sat over its edge and said, "Bring me a bucket of its water." When it was brought, he spat and invoked (Allah) and said, "Leave it for a while." Then they quenched their thirst and watered their riding animals (from that well) till they departed.  

أَنْبَأَنَا الْبَرَاءُ بْنُ عَازِبٍ ؓ أَنَّهُمْ كَانُوا مَعَ رَسُولِ اللَّهِ ﷺ يَوْمَ الْحُدَيْبِيَةِ أَلْفًا وَأَرْبَعَمِائَةٍ أَوْ أَكْثَرَ فَنَزَلُوا عَلَى بِئْرٍ فَنَزَحُوهَا فَأَتَوْا رَسُولَ اللَّهِ ﷺ فَأَتَى الْبِئْرَ وَقَعَدَ عَلَى شَفِيرِهَا ثُمَّ قَالَ ائْتُونِي بِدَلْوٍ مِنْ مَائِهَا فَأُتِيَ بِهِ فَبَصَقَ فَدَعَا ثُمَّ قَالَ دَعُوهَا سَاعَةً فَأَرْوَوْا أَنْفُسَهُمْ وَرِكَابَهُمْ حَتَّى ارْتَحَلُوا
