Sahih al-Bukhari 4702Book 65, Hadith 224
حَدَّثَنَا إِبْرَاهِيمُ بْنُ الْمُنْذِرِ، حَدَّثَنَا مَعْنٌ، قَالَ حَدَّثَنِي مَالِكٌ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ ـ رضى الله عنهما ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ لأَصْحَابِ الْحِجْرِ " لاَ تَدْخُلُوا عَلَى هَؤُلاَءِ الْقَوْمِ إِلاَّ أَنْ تَكُونُوا بَاكِينَ فَإِنْ لَمْ تَكُونُوا بَاكِينَ فَلاَ تَدْخُلُوا عَلَيْهِمْ أَنْ يُصِيبَكُمْ مِثْلُ مَا أَصَابَهُمْ ".
(While we were going for the Battle of Tabuk and when we reached the places of the dwellers of Al- Hijr), Allah's Messenger (ﷺ) said about the dwellers of Al-Hijr (to us). "Do not enter (the dwelling places) of these people unless you enter weeping, but if you weep not, then do not enter upon them, lest you be afflicted with what they were afflicted with."
