The Prophet ﷺ said: People who get up from an assembly in which they did not remember Allah will be just as if they had got up from an ass's corpse, and it will be a cause of grief to them.
قَالَ رَسُولُ اللَّهِ ﷺ مَا مِنْ قَوْمٍ يَقُومُونَ مِنْ مَجْلِسٍ لاَ يَذْكُرُونَ اللَّهَ فِيهِ إِلاَّ قَامُوا عَنْ مِثْلِ جِيفَةِ حِمَارٍ وَكَانَ لَهُمْ حَسْرَةً
[Machine] The Messenger of Allah ﷺ said, "No group of people sits together without remembering Allah, except that they will disperse from that gathering as if they were fleeing from a donkey's fart. And that gathering will be a source of regret for them on the Day of Resurrection."
أَنَّ رَسُولَ اللهِ ﷺ قَالَ مَا جَلَسَ قَوْمٌ مَجْلِسًا فَتَفَرَّقُوا عَنْ غَيْرِ ذِكْرِ اللهِ إِلَّا تَفَرَّقُوا عَنْ مِثْلِ جِيفَةِ حِمَارٍ وَكَانَ ذَلِكَ الْمَجْلِسُ حَسْرَةً عَلَيْهِمْ يَوْمَ الْقِيَامَةِ
[Machine] The Messenger of Allah ﷺ said, "There is no group of people who sit together and do not mention Allah in their gathering except that they will have regret on the Day of Judgment. Even if they enter Paradise."
قَالَ رَسُولُ اللهِ ﷺ «مَا مِنْ قَوْمٍ يَجْلِسُونَ مَجْلِسًا لَا يَذْكُرُونَ اللهَ فِيهِ إِلَّا كَانَتْ عَلَيْهِمْ حَسْرَةٌ يَوْمَ الْقِيَامَةِ وَإِنْ دَخَلُوا الْجَنَّةَ»
"مَا تَفرَّقَ قَوْمٌ مِنْ مَجْلسٍ لَمْ يَذْكُروا اللهَ إِلّا تفَرَّقُوا عن مثلِ جيفةِ الحِمَارِ، وَكَانَ عَلَيهُمْ حَسْرةً يومَ القِيَامَةِ".
"مَا مِنْ قوْمٍ يَقُومُونَ مِنْ مَجْلِسٍ لا يَذْكُرُونَ الله فِيهِ إلا قامُوا عَنْ مِثْلِ جيفَةِ حِمَارٍ، وكانَ ذَلِكَ المجلِسُ علَيهِمْ حَسْرةً يَوْمَ القِيامةِ".
