Abu Hurairah reported:
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.
حَدَّثَنَا أَحْمَدُ بْنُ عَمْرِو بْنِ السَّرْحِ، وَابْنُ، عَبْدَةَ - فِي آخَرِينَ وَهَذَا لَفْظُ ابْنِ عَبْدَةَ - أَخْبَرَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ أَعْرَابِيًّا، دَخَلَ الْمَسْجِدَ وَرَسُولُ اللَّهِ صلى الله عليه وسلم جَالِسٌ فَصَلَّى - قَالَ ابْنُ عَبْدَةَ - رَكْعَتَيْنِ ثُمَّ قَالَ اللَّهُمَّ ارْحَمْنِي وَمُحَمَّدًا وَلاَ تَرْحَمْ مَعَنَا أَحَدًا . فَقَالَ النَّبِيُّ صلى الله عليه وسلم " لَقَدْ تَحَجَّرْتَ وَاسِعًا " . ثُمَّ لَمْ يَلْبَثْ أَنْ بَالَ فِي نَاحِيةِ الْمَسْجِدِ فَأَسْرَعَ النَّاسُ إِلَيْهِ فَنَهَاهُمُ النَّبِيُّ صلى الله عليه وسلم وَقَالَ " إِنَّمَا بُعِثْتُمْ مُيَسِّرِينَ وَلَمْ تُبْعَثُوا مُعَسِّرِينَ صُبُّوا عَلَيْهِ سَجْلاً مِنْ مَاءٍ " . أَوْ قَالَ " ذَنُوبًا مِنْ مَاءٍ " .
