عَنْ أَنَسٍ رَضِيَ اللَّهُ عَنْهُ قَالَ مَرَرْتُ مَعَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فِي طَرِيقِ الْمَدِينَةِ فَرَأَى قُبَّةً مِنْ لَبِنٍ فَقَالَ ((لِمَنْ هَذِهِ)) فَقُلْتُ لِفُلَانٍ فَقَالَ ((أَمَا إِنَّ كُلَّ بِنَاءٍ هَدٌّ عَلَى صَاحِبِهِ يَوْمَ الْقِيَامَةِ إِلَّا مَا كَانَ فِي مَسْجِدٍ)) أَوْ فِي بِنَاءِ مَسْجِدٍ شَكَّ أَسْوَدُ ثُمَّ مَرَّ فَلَمْ يَرَهَا فَقَالَ ((مَا فَعَلَتِ الْقُبَّةُ)) قُلْتُ بَلَغَ صَاحِبَهَا مَا قُلْتَ فَهَدَمَهَا قَالَ ((رَحِمَهُ اللَّهُ))
It is narrated from Sayyiduna Anas (may Allah be pleased with him), he says: I was walking with the Noble Prophet (peace and blessings be upon him) on a road in Madinah Munawwarah. On the way, the Prophet (peace and blessings be upon him) saw a dome made of unbaked bricks and asked: Whose is this? I said: Yes, it belongs to such-and-such person. The Prophet (peace and blessings be upon him) said: Beware! Every building will be thrown down upon its owner on the Day of Resurrection, except that which is used for the construction of a mosque, or for such-and-such matters. Later, when the Prophet (peace and blessings be upon him) passed by the same road, he did not see the dome. The Prophet (peace and blessings be upon him) asked: What happened to that dome? I said: When your words reached its owner, he demolished it. The Prophet (peace and blessings be upon him) said: May Allah have mercy on him.
