وعن أبي هريرة رَضِيَ اللَّهُ عَنهُ
قال، قال رَسُول اللَّهِ صلى الله عليه وسلم: «ما من قوم يقومون من مجلس ولا يذكرون اللَّه تعالى فيه إلا قاموا عن مثل جيفة حمار وكان لهم حسرة»
Messenger of Allah (sallallahu alayhi wa sallam) said, “Those people who leave a gathering in which they have not remembered Allah, will conclude it as if it has foul odour similar to that of a rotten carcass of a donkey. And it will be a cause of grief to them.”.
