Hadith 2282
وَعَنْ مَالِكٍ قَالَ: بَلَغَنِي أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ يَقُولُ: «ذَاكِرُ اللَّهِ فِي الْغَافِلِينَ كَالْمُقَاتِلِ خَلْفَ الْفَارِّينَ وَذَاكِرُ اللَّهِ فِي الْغَافِلِينَ كَغُصْنٍ أَخْضَرَ فِي شَجَرٍ يَابِس»
Malik said he heard God’s messenger used to say, “The one who makes mention of God among those who are negligent is like one who goes on fighting after others have fled; the one who makes mention of God among those who are negligent is like a green branch upon a withered tree.
