He saw the Messenger of Allah perform ablution then take a handful of water and sprinkle it over his private area to remove any doubts about urine drippings. (Using translation from Ibn Mājah 461)   

«أَنَّ رَسُولَ اللهِ ﷺ كَانَ إِذَا تَوَضَّأَ أَخَذَ كَفًّا مِنْ مَاءٍ فَنَضَحَ بِهِ فَرْجَهُ»  

[Machine] The Banu Shababa tribe had a valley full of intelligence. They used to deliver to the Messenger of Allah, ﷺ , honey from a bee colony they owned, with ten portions from every ten portions. They also had two valleys which they protected. When Umar became the caliph, he appointed Sufyan ibn Abdullah al-Thaqafi to manage their affairs. They refused to deliver anything to him and said that they only used to deliver it to the Messenger of Allah, ﷺ . So, Sufyan wrote a letter to Umar informing him of this and Umar wrote back to him saying, "Indeed, bees are flies of sustenance that Allah sends to whom He wills. If they deliver to you what they used to deliver to the Messenger of Allah, ﷺ , then give them their valleys. If not, then create a separation between them and the people. They should deliver to him what they used to deliver to the Messenger of Allah, ﷺ , and protect their valleys."  

أَنَّ بَنِي شَبَابَةَ بَطْنٌ مِنْ فَهْمٍ كَانُوا يُؤَدُّونَ إِلَى رَسُولِ اللهِ ﷺ عَلَى نَحْلٍ كَانَ لَهُمُ الْعُشْرَ مِنْ كُلِّ عَشْرِ قِرَبٍ قِرْبَةٌ وَكَانَ يَحْمِي وَادِيَيْنِ لَهُمْ فَلَمَّا كَانَ عُمَرُ ؓ اسْتَعْمَلَ عَلَى مَا هُنَاكَ سُفْيَانَ بْنَ عَبْدِ اللهِ الثَّقَفِيَّ فَأَبَوْا أَنْ يُؤَدُّوا إِلَيْهِ شَيْئًا وَقَالُوا إِنَّمَا كُنَّا نُؤَدِّيهِ إِلَى رَسُولِ اللهِ ﷺ فَكَتَبَ سُفْيَانُ إِلَى عُمَرَ ؓ بِذَلِكَ فَكَتَبَ إِلَيْهِ عُمَرُ ؓ «إِنَّمَا النَّحْلُ ذُبَابُ غَيْثٍ يَسُوقُهُ اللهُ ﷻ رِزْقًا إِلَى مَنْ يَشَاءُ فَإِنْ أَدُّوا إِلَيْكَ مَا كَانُوا يُؤَدُّونَ إِلَى رَسُولِ اللهِ ﷺ فَاحْمِ لَهُمْ أَوْدِيَتَهُمْ وَإِلَّا فَخَلِّ بَيْنَهُ وَبَيْنَ النَّاسِ فَأَدَّوْا إِلَيْهِ مَا كَانُوا يُؤَدُّونَ إِلَى رَسُولِ اللهِ ﷺ وَحَمَى لَهُمْ أَوْدِيَتَهُمْ»
