Narrated Ibn Umar:

Allah's Apostle ﷺ said to his companions who were at Al-Hijr, "Do not enter upon these people who are being punished, except in a weeping state, lest the same calamity as of theirs should befall you..."

حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ، حَدَّثَنَا مَالِكٌ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ قَالَ قَالَ رَسُولُ اللَّهِ ﷺ لأَصْحَابِ الْحِجْرِ
" لاَ تَدْخُلُوا عَلَى هَؤُلاَءِ الْمُعَذَّبِينَ إِلاَّ أَنْ تَكُونُوا بَاكِينَ، أَنْ يُصِيبَكُمْ مِثْلُ مَا أَصَابَهُمْ ".
