Ubaydullah bin al-Qibtiyyah relates: Al-Harith bin Abi Rabi'ah and Abdullah bin Safwan went in to Sayyidah Umm Salamah (may Allah be pleased with her), and I was with them. They asked her about the army that will be swallowed up by the earth, and this was in the time of Ibn al-Zubayr (may Allah be pleased with them both). She said: the Messenger of Allah (peace and blessings be upon him) said: "One seeking refuge will take refuge in the House (the Ka'bah), and Allah will send an army; when they reach al-Bayda', they will be swallowed up by the earth." She said: O Messenger of Allah! Will the one among them who was unwilling also be swallowed up? He (peace and blessings be upon him) said: "He will be swallowed up along with them, but on the Day of Resurrection he will be raised according to his intention."

Sayyidah Umm Salamah (may Allah be pleased with her) said: the Messenger of Allah (peace and blessings be upon him) said: "An army will attack this House, until, when they reach al-Bayda', they will be swallowed up by the earth." I said: O Messenger of Allah! What about the one who is coerced? He (peace and blessings be upon him) said: "He will be raised according to his intention."
