عَن الْمِقْدَاد بن الْأسود قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: " يَقُولُ لَا يَبْقَى عَلَى ظَهْرِ الْأَرْضِ بَيْتُ مَدَرٍ وَلَا وَبَرٍ إِلَّا أَدْخَلَهُ اللَّهُ كلمة الاسلام بعز عَزِيز أَو ذل ذليل إِمَّا يعزهم الله عز وَجل فَيَجْعَلُهُمْ مِنْ أَهْلِهَا أَوْ يُذِلُّهُمْ فَيَدِينُونَ لَهَا رَوَاهُ أَحْمد

Miqdad reported that he heard God’s messenger say, “There will not remain on the face of the earth a mud-brick house or a camel’s hair tent which God will not cause the confession of Islam to enter bringing both mighty honour and abject abasement. God will either honour the occupants and put them among its adherents, or will humiliate them and they will be subject to it.” Miqdad said, “God will then receive complete obedience.” Ahmad transmitted it.
