Messenger of Allah ﷺ stood up for the prayer and we too stood up along with him. Then a bedouin shouted while offering prayer. "O Allah! Bestow Your Mercy on me and Muhammad only and do not bestow it on anybody else along with us." When the Prophet ﷺ had finished his prayer with Taslim, he said to the Bedouin, "You have limited (narrowed) a very vast (thing)," meaning Allah's Mercy.  

قَامَ رَسُولُ اللَّهِ ﷺ فِي صَلاَةٍ وَقُمْنَا مَعَهُ فَقَالَ أَعْرَابِيٌّ وَهْوَ فِي الصَّلاَةِ اللَّهُمَّ ارْحَمْنِي وَمُحَمَّدًا وَلاَ تَرْحَمْ مَعَنَا أَحَدًا فَلَمَّا سَلَّمَ النَّبِيُّ ﷺ قَالَ لِلأَعْرَابِيِّ لَقَدْ حَجَّرْتَ وَاسِعًا يُرِيدُ رَحْمَةَ اللَّهِ  

A Bedouin entered the masjid and prayed two rak'ahs, then he said: "O Allah, have mercy on me and on Muhammad and do not have mercy on anyone else." The Messenger of Allah ﷺ said: "You have limited something vast."  

أَنَّ أَعْرَابِيًّا دَخَلَ الْمَسْجِدَ فَصَلَّى رَكْعَتَيْنِ ثُمَّ قَالَ اللَّهُمَّ ارْحَمْنِي وَمُحَمَّدًا وَلاَ تَرْحَمْ مَعَنَا أَحَدًا فَقَالَ رَسُولُ اللَّهِ ﷺ لَقَدْ تَحَجَّرْتَ وَاسِعًا  

Abu Hurairah said; The Messenger of Allah (May peace be upon him) got up for the prayer and we also stood up along with him. A Bedouin said said during prayer; O Allah, show mercy to me and to Muhammed and do not show mercy to anyone along with us. When the Messenger of Allah (May peace be upon him) uttered the salutation, he said to the Bedouin; you narrowed down a vast (thing). By this he meant the mercy of Allah.
