Silsilah as-Sahihah 3663 — Story of Gog and Magog

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) said: "Today, a hole as big as this has been made in the great barrier of Gog and Magog." Wahib (clarifying the matter) made a knot of ninety (90) and joined his fingers together.
