He reported God's messenger as saying, "People who arise from an assembly in which they did not remember God will be just as if they had got up from an ass's corpse, and it will be a cause of grief to them." Ahmad and Abu Dawud transmitted it.
Reported by Abu Dawud (No. 4855). Cited in Mishkat al-Masabih (No. 2273).
"No people leave a gathering in which they did not remember Allah except that it will be as if they are leaving the carcass of a donkey, and it will be a cause of regret for them."
وعنه عن النبي صلى الله عليه وسلم قال: "ما جلس قوم مجلساً لم يذكروا الله تعالى فيه، ولم يصلوا على نبيهم فيه، إلا كان عليهم ترة؛ فإن شاء عذبهم، وإن شاء غفر لهم" ((رَوَاهُ التِّرمِذِيُّ وَقَالَ: "حَدِيثٌ حَسَنٌ")).
