[Machine] The Messenger of Allah ﷺ used to perform ablution for every prayer until the day of the conquest of Mecca, where he performed all prayers with a single ablution and wiped over his socks. Umar said to him, "I saw you do something you didn't used to do?" He replied, "I deliberately did it, O Umar." Abu Muhammad said, "The action of the Messenger of Allah ﷺ indicates that the meaning of Allah's saying, 'When you rise to prayer, wash your faces' (Surah Al-Maidah 5:6) applies to every person who is impure and this includes the statement of the Prophet ﷺ , 'There is no ablution except from impurity.' And Allah knows best."  

كَانَ رَسُولُ اللَّهِ ﷺ يَتَوَضَّأُ لِكُلِّ صَلَاةٍ حَتَّى كَانَ يَوْمُ فَتْحِ مَكَّةَ صَلَّى الصَّلَوَاتِ بِوُضُوءٍ وَاحِدٍ وَمَسَحَ عَلَى خُفَّيْهِ فَقَالَ لَهُ عُمَرُ رَأَيْتُكَ صَنَعْتَ شَيْئًا لَمْ تَكُنْ تَصْنَعُهُ؟ قَالَ «إِنِّي عَمْدًا صَنَعْتُ يَا عُمَرُ» قَالَ أَبُو مُحَمَّدٍ فَدَلَّ فِعْلُ رَسُولِ اللَّهِ ﷺ أَنَّ مَعْنَى قَوْلِ اللَّهِ تَعَالَى {إِذَا قُمْتُمْ إِلَى الصَّلَاةِ فَاغْسِلُوا وُجُوهَكُمْ} [المائدة 6] الْآيَةَ لِكُلِّ مُحْدِثٍ لَيْسَ لِلطَّاهِرِ ومنْهُ قوْلُ النَّبيِّ ﷺ «لَا وُضُوءَ إِلَّا مِنْ حَدَثٍ» وَاللَّهُ أَعْلَمُ
