Bulugh al-Maram 265
Narrated Anas (RA):
Allah's Messenger (ﷺ) said: "The rewards of my Ummah (followers) were shown to me, even a peck of dust a man takes out of the mosque." [Reported by Abu Dawud and at-Tirmidhi. The latter graded it Gharib (having a single narrator), and Ibn Khuzaimah graded it Sahih (authentic)].
وَعَنْ أَنَسٍ ‏- رضى الله عنه ‏- قَالَ : قَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-{ عُرِضَتْ عَلَيَّ أُجُورُ أُمَّتِي , حَتَّى اَلْقَذَاةُ يُخْرِجُهَا اَلرَّجُلُ مِنْ اَلْمَسْجِدِ } رَوَاهُ أَبُو دَاوُدَ , وَاَلتِّرْمِذِيُّ وَاسْتَغْرَبَهُ , وَصَحَّحَهُ اِبْنُ خُزَيْمَةَ .‏ 1
