Circumstances which make ablution necessary - Section 1
وَعَنْ بُرَيْدَةَ: أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ صَلَّى الصَّلَوَات يَوْم الْفَتْح بِوضُوء وَاحِد وَمسح عل خُفَّيْهِ فَقَالَ لَهُ عُمَرُ: لَقَدْ صَنَعْتَ الْيَوْمَ شَيْئًا لَمْ تَكُنْ تَصْنَعُهُ فَقَالَ: «عَمْدًا صَنَعْتُهُ يَا عمر» . رَوَاهُ مُسلم
Buraida said that God’s messenger prayed the prayers on the day of the Conquest [The conquest of Mecca in the year 8 A.H.] with one ablution and wiped over his shoes. ‘Umar said, “You have done something today that you have not been accustomed to do.” He replied, “I have done it purposely, ‘Umar.” Muslim transmitted it.
