Sahih Muslim Book - 5, Hadith - 1165

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِى شَيْبَةَ حَدَّثَنَا مُحَمَّدُ بْنُ فُضَيْلٍ عَنْ أَبِى مَالِكٍ الأَشْجَعِىِّ عَنْ رِبْعِىٍّ عَنْ حُذَيْفَةَ قَالَ قَالَ رَسُولُ اللَّهِ -صلى الله عليه وسلم- « فُضِّلْنَا عَلَى النَّاسِ بِثَلاَثٍ جُعِلَتْ صُفُوفُنَا كَصُفُوفِ الْمَلاَئِكَةِ وَجُعِلَتْ لَنَا الأَرْضُ كُلُّهَا مَسْجِدًا وَجُعِلَتْ تُرْبَتُهَا لَنَا طَهُورًا إِذَا لَمْ نَجِدِ الْمَاءَ ». وَذَكَرَ خَصْلَةً أُخْرَى.

It was narrated that Hudhaifah said: "The Messenger of Allah (s.a.w) said: 'We have been favored over the people in three things: Our rows (in prayer) have been made like the rows of the Angels; the whole earth has been made a place of prostration for us, and its dust has been made a means of purification if water cannot be found,' and he mentioned another thing."
