Sahih Muslim 135c
وَحَدَّثَنِي عَبْدُ اللَّهِ بْنُ الرُّومِيِّ، حَدَّثَنَا النَّضْرُ بْنُ مُحَمَّدٍ، حَدَّثَنَا عِكْرِمَةُ، - وَهُوَ ابْنُ عَمَّارٍ - حَدَّثَنَا يَحْيَى، حَدَّثَنَا أَبُو سَلَمَةَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ لِي رَسُولُ اللَّهِ صلى الله عليه وسلم " لاَ يَزَالُونَ يَسْأَلُونَكَ يَا أَبَا هُرَيْرَةَ حَتَّى يَقُولُوا هَذَا اللَّهُ فَمَنْ خَلَقَ اللَّهَ " قَالَ فَبَيْنَا أَنَا فِي الْمَسْجِدِ إِذْ جَاءَنِي نَاسٌ مِنَ الأَعْرَابِ فَقَالُوا يَا أَبَا هُرَيْرَةَ هَذَا اللَّهُ فَمَنْ خَلَقَ اللَّهَ قَالَ فَأَخَذَ حَصًى بِكَفِّهِ فَرَمَاهُمْ ثُمَّ قَالَ قُومُوا قُومُوا صَدَقَ خَلِيلِي .
'Abdullah ibn al-Rumi narrated to me: al-Nadr ibn Muhammad narrated to us; 'Ikrima—who is Ibn 'Ammar—narrated to us; Yahya narrated to us; Abu Salama narrated to us, from Abu Hurayra, who said: The Messenger of Allah (peace and blessings be upon him) said to me: They will keep asking you, Abu Hurayra, until they say, Here is Allah—so who created Allah? He said: While I was in the mosque, some Bedouins came to me and said, Abu Hurayra, here is Allah—so who created Allah? He said: I took a handful of pebbles and threw them at them, then said, Get up, get up! My close friend spoke the truth.
