A man came to the Prophet; he had performed ablution and has missed a spot the size of a fingernail where water had not reached. The Prophet said to him: 'Go back and perform ablution properly.'"
أَنَّ رَجُلاً أَتَى النَّبِيَّ ﷺ وَقَدْ تَوَضَّأَ وَتَرَكَ مَوْضِعَ الظُّفْرِ لَمْ يُصِبْهُ الْمَاءُ فَقَالَ لَهُ النَّبِيُّ ﷺ ارْجِعْ فَأَحْسِنْ وُضُوءَكَ
A person came to the Messenger of Allah ﷺ. He performed ablution and left a small part equal to the space of a nail upon his foot. The Messenger of Allah ﷺ said to him : Go back and perform ablution well. Abu Dawud said: This tradition is not known through Jarir b. Hazim. It was transmitted only by Ibn Wahab. Another version adds the wording : “ Go back and perform the ablution well.”
أَنَّ رَجُلاً جَاءَ إِلَى النَّبِيِّ ﷺ وَقَدْ تَوَضَّأَ وَتَرَكَ عَلَى قَدَمَيْهِ مِثْلَ مَوْضِعِ الظُّفْرِ فَقَالَ لَهُ رَسُولُ اللَّهِ ﷺ ارْجِعْ فَأَحْسِنْ وُضُوءَكَ
