Mishkat al-Masabih #38

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.
