Whenever the Prophet ﷺ went to answer the call of nature, I used to bring water with which he used to clean his private parts.  

البخاري:٢١٧حَدَّثَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ قَالَ حَدَّثَنَا إِسْمَاعِيلُ بْنُ إِبْرَاهِيمَ قَالَ حَدَّثَنِي رَوْحُ بْنُ الْقَاسِمِ قَالَ حَدَّثَنِي عَطَاءُ بْنُ أَبِي مَيْمُونَةَ عَنْ أَنَسِ بْنِ مَالِكٍ قَالَ

كَانَ النَّبِيُّ ﷺ إِذَا تَبَرَّزَ لِحَاجَتِهِ أَتَيْتُهُ بِمَاءٍ فَيَغْسِلُ بِهِ

The Messenger of Allah ﷺ went to a far-off place in the desert (hidden from the sight of human beings) for relieving himself. Then I brought water for him and he cleansed himself.
