Bara bin Azib reported,

You consider the conquest of Makkah to be the great victory, and the conquest of Makkah was indeed a victory, but we consider the great victory to be the Pledge of Ridwan on the day of Hudaybiyyah.We were with the Prophet ﷺ that day, fourteen hundred strong. Hudaybiyyah was a well, and we drew from it until not a single drop remained. News of this reached the Prophet ﷺ, so he came to the well and sat at its edge. He called for a vessel of water, performed ablution, then rinsed his mouth and made supplication, after which he poured the water back into the well. We left it alone for only a short while, then it gave us all the water we wanted, both for ourselves and for our mounts.

حدثنا عبيد الله بن موسى عن إسرائيل عن أبي إسحاق

عن البراء رضي الله عنه قال

تعدون أنتم الفتح فتح مكة وقد كان فتح مكة فتحا ونحن نعد الفتح بيعة الرضوان يوم الحديبية كنا مع النبي ﷺ أربع عشرة مائة والحديبية بئر فنزحناها فلم نترك فيها قطرة فبلغ ذلك النبي ﷺ فأتاها فجلس على شفيرها ثم دعا بإناء من ماء فتوضأ ثم مضمض ودعا ثم صبه فيها فتركناها غير بعيد ثم إنها أصدرتنا ما شئنا نحن وركابنا
