Riyad as-Salihin

Narrated 'A'ishah (May Allah be pleased with her) reported: Messenger of Allah (ﷺ) said, "An army will raid the Ka'bah and when it reaches a desert land, all of them will be swallowed up by the earth." She asked; "O Messenger of Allah! Why all of them?" He answered, "All of them will be swallowed by the earth but they will be raised for Judgement according to their intentions."
