HADITH OF THE DAY
WALL OF GOG & MAGOG
Narrated by Zainab bint Jahsh
That the Prophet (Peace & Blessings of Allah upon Him) once came to her in a state of fear & said,
"None has the right to be worshipped but Allah. Woe unto the Arabs from a danger that has come near. An opening has been made in the wall of Gog & Magog."
