Sahih al-Bukhari, Hadith 4150 ⓘ

Narrated Al-Bara: Do you (people) consider the conquest of Mecca, the Victory (referred to in the Qur'an 48:1). Was the conquest of Mecca a victory? We really consider that the actual Victory was the Ar-Ridwan Pledge of allegiance which we gave on the day of Al-Hudaibiya (to the Prophet). On the day of Al-Hudaibiya we were fourteen hundred men along with the Prophet Al-Hudaibiya was a well, the water of which we used up leaving not a single drop of water in it. When the Prophet was informed of that, he came and sat on its edge. Then he asked for a utensil of water, performed ablution from it, rinsed (his mouth), invoked (Allah), and poured the remaining water into the well. We stayed there for a while and then the well brought forth what we required of water for ourselves and our riding animals.

حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُوسَى، عَنْ إِسْرَائِيلَ، عَنْ أَبِي إِسْحَاقَ، عَنِ الْبَرَاءِ ـ رضى الله عنه ـ قَالَ تَعُدُّونَ أَنْتُمُ الْفَتْحَ فَتْحَ مَكَّةَ، وَقَدْ كَانَ فَتْحُ مَكَّةَ فَتْحًا، وَنَحْنُ نَعُدُّ الْفَتْحَ بَيْعَةَ الرُّضْوَانِ يَوْمَ الْحُدَيْبِيَةِ‏.‏ كُنَّا مَعَ النَّبِيِّ صلى الله عليه وسلم أَرْبَعَ عَشْرَةَ مِائَةً، وَالْحُدَيْبِيَةُ بِئْرٌ فَنَزَحْنَاهَا، فَلَمْ نَتْرُكْ فِيهَا قَطْرَةً، فَبَلَغَ ذَلِكَ النَّبِيَّ صلى الله عليه وسلم فَأَتَاهَا، فَجَلَسَ عَلَى شَفِيرِهَا، ثُمَّ دَعَا بِإِنَاءٍ مِنْ مَاءٍ فَتَوَضَّأَ ثُمَّ مَضْمَضَ وَدَعَا، ثُمَّ صَبَّهُ فِيهَا فَتَرَكْنَاهَا غَيْرَ بَعِيدٍ ثُمَّ إِنَّهَا أَصْدَرَتْنَا مَا شِئْنَا نَحْنُ وَرِكَابَنَا‏.‏
