It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that in the blessed time of the Prophet (peace and blessings be upon him) a sinking of the earth towards the east was mentioned. Some people said: "O Messenger of Allah (peace and blessings be upon him), will a land in which there are Muslims also be made to sink?" He (peace and blessings be upon him) said: "Yes, when most of its inhabitants become wicked (evildoers)."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Yahya bin Sa'id (may Allah have mercy on him) except Anas (bin Iyad) (may Allah have mercy on him), and al-Musayyibi (may Allah have mercy on him) is alone in narrating it from him."
