حَدَّثَنَا سُفْيَانُ حَدَّثَنِي عَبْدُ اللَّهِ بْنُ دِينَارٍ عَنِ ابْنِ عُمَرَ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ لَا تَدْخُلُوا عَلَى هَؤُلَاءِ الْقَوْمِ الَّذِينَ عُذِّبُوا إِلَّا أَنْ تَكُونُوا بَاكِينَ فَإِنْ لَمْ تَكُونُوا بَاكِينَ فَلَا تَدْخُلُوا عَلَيْهِمْ فَإِنِّي أَخَافُ أَنْ يُصِيبَكُمْ مِثْلُ مَا أَصَابَهُمْ
مسند امام احمد بن حنبل · Hadith 4561
It was narrated from Ibn Umar, from the Prophet (PBUH) who said; "Do not enter upon these people who have been punished, unless you are weeping. If you are not weeping then do not enter upon them, for I fear that there may befall you the like of what befell them."
