وَعَنْ أَبِي هُرَيْرَةَ وَابْنِ مَسْعُودٍ وَابْنِ عُمَرَ عَنِ
النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «مَنْ تَوَضَّأَ وَذَكَرَ اسْمَ اللَّهِ فَإِنَّهُ يُطَهِّرُ جَسَدَهُ كُلَّهُ وَمَنْ تَوَضَّأَ وَلَمْ يَذْكُرِ اسْمَ الله لم يطهر إِلَّا مَوضِع الْوضُوء»
Abu Hurayrah, Ibn Masud and Ibn Umar reported the Prophet (sallallahu alayhi wa sallam) as saying, “He who performs ablution and mentions God’s name purifies his whole body, but he who performs ablution and does not mention God’s name is pure only where the ablution reached.”
