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»
The Prophet (sallallahu alayhi wa sallam) said, “Whenever a group of people sit in a gathering in which they do not remember Allah the Exalted, nor supplicate to elevate the rank of their Prophet, such a gathering will be a cause of grief to them. If Allah wills, He will punish them, and if He wills He will forgive them.”.
