"A Bedouin entered the Masjid while the Prophet was sitting. He prayed, then when he was finished, he said: 'O Allah! Have mercy upon me and Muhammad, and do not have mercy on anyone along with us.' The Prophet turned, towards him and said: 'You have restricted something that is unrestricted.' It was not long before he was urinating in the Masjid. So the people rushed to him. But Prophet said: 'Pour a bucket of water over it - or - a tumbler of water over it.' Then he said: 'You have been sent to make things easy (for the people); you have not been sent to make things difficult for them.'"  

دَخَلَ أَعْرَابِيٌّ الْمَسْجِدَ وَالنَّبِيُّ ﷺ جَالِسٌ فَصَلَّى فَلَمَّا فَرَغَ قَالَ اللَّهُمَّ ارْحَمْنِي وَمُحَمَّدًا وَلاَ تَرْحَمْ مَعَنَا أَحَدًا فَالْتَفَتَ إِلَيْهِ النَّبِيُّ ﷺ فَقَالَ لَقَدْ تَحَجَّرْتَ وَاسِعًا فَلَمْ يَلْبَثْ أَنْ بَالَ فِي الْمَسْجِدِ فَأَسْرَعَ إِلَيْهِ النَّاسُ فَقَالَ النَّبِيُّ ﷺ أَهْرِيقُوا عَلَيْهِ سَجْلاً مِنْ مَاءٍ أَوْ دَلْوًا مِنْ مَاءٍ ثُمَّ قَالَ إِنَّمَا بُعِثْتُمْ مُيَسِّرِينَ وَلَمْ تُبْعَثُوا مُعَسِّرِينَ  

A bedouin entered the mosque while the Messenger of Allah ﷺ was sitting. He offered two rak'ahs of prayer, according to the version of Ibn 'Abdah. He then said: O Allah, have mercy on me and on Muhammad and do not have mercy on anyone along with us. The Prophet ﷺ said: You have narrowed down (a thing) that was broader. After a short while he passed a water in the corner of the mosque. The people rushed towards him. The Prophet ﷺ prevented them and said: You have been sent to facilitate and not create difficulties. Pour a bucket of water upon it. (Using translation from Abū Dāʾūd 380)   

دَخَلَ أَعْرَابِيٌّ الْمَسْجِدَ فَصَلَّى رَكْعَتَيْنِ ثُمَّ قَالَ اللهُمَّ ارْحَمْنِي وَمُحَمَّدًا وَلَا تَرْحَمْ مَعَنَا أَحَدًا فَالْتَفَتَ إِلَيْهِ النَّبِيُّ ﷺ فَقَالَ لَقَدْ تَحَجَّرْتَ وَاسِعًا ثُمَّ لَمْ يَلْبَثْ أَنْ بَالَ فِي الْمَسْجِدِ فَأَسْرَعَ النَّاسُ إِلَيْهِ فَقَالَ لَهُمْ رَسُولُ اللهِ ﷺ إِنَّمَابُعِثْتُمْ مُيَسِّرِينَ وَلَمْ تُبْعَثُوا مُعَسِّرِينَ أَهْرِيقُوا عَلَيْهِ دَلْوًا مِنْ مَاءٍ أَوْ سَجْلًا مِنْ مَاءٍ  

"عَنْ أَبِي هُرَيْرَةَ قَالَ: جَاءَ أَعْرَابِيٌّ إِلَى النَّبِيِّ ﷺ وَهُو قَاعِدٌ فَصَلَّى ركْعَتَين وَقَالَ: اللَّهُمَّ ارْحَمني وارْحَمْ مُحُمَّدًا، ولا تَرْحَم مَعَنَا أَحَدًا، فَالْتَفَتَ إِلَيْهِ النَّبِيُّ ﷺ وَقَالَ: تَحَجَّرتَ واسِعًا فَلَمْ يَلْبَثْ الأَعْرَابِيُّ أن تَنَحَّى فَبَالَ فِي نَاحِيةِ الْمسْجِدِ، فَعجلَ إِلَيْهِ أَصْحَابُ النَّبِيِّ ﷺ فَقَالَ النَّبِيُّ ﷺ : صُبُّوا عَلَيْهِ ذَنُوبًا مِنْ مَاءٍ، أَوْ سجْلًا إِنَّما بُعِثْتمُ مُيَسِّرِين ولم تُبْعُثوا مُعَسِّرينَ".
