عَنْ أَبِي ذَرٍّ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ عُرِضَتْ عَلَيَّ أَعْمَالُ أُمَّتِي حَسَنُهَا وَسَيِّئُهَا فَرَأَيْتُ فِي مَحَاسِنِ أَعْمَالِهَا الْأَذَى يُمَاطُ عَنِ الطَّرِيقِ وَرَأَيْتُ فِي مَسَاوِي أَعْمَالِهَا النُّخَامَةَ تَكُونُ فِي الْمَسْجِدِ لَا تُدْفَنُ
Sayyiduna Abu Dharr (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: The good and bad deeds of my Ummah were presented before me. Among the good deeds, I saw the removal of a harmful thing from the road, and among the bad deeds, I saw phlegm in the mosque which had not been buried.
