عَنْ ثَابِتِ بْنِ أَبِي صَفِيَّةَ قَالَ: قُلْتُ لِأَبِي جَعْفَرٍ هُوَ مُحَمَّدٌ الْبَاقِرُ حَدَّثَكَ جَابِرٌ: أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ تَوَضَّأَ مرّة مرّة ومرتين مرَّتَيْنِ وَثَلَاثًا ثَلَاثًا. قَالَ: نعم. رَوَاهُ التِّرْمِذِيّ وَابْن مَاجَه

Abu Huraira, Ibn Mas'ud and Ibn ‘Umar reported the Prophet 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.”
