Hadith 767
Sayyiduna Anas bin Malik (may Allah be pleased with him) says: During the time of the Prophet (peace and blessings be upon him), the sinking of the earth towards the east was mentioned, so some people said: Will the land in which Muslims live also sink? The Prophet (peace and blessings be upon him) said: "Yes! When the majority there becomes involved in sin and immorality."
Hadith 768
Sayyiduna Ibn Abbas (may Allah be pleased with them both) reports that the Prophet (peace and blessings be upon him) said: "Some people from this Ummah will spend the night in eating, drinking, and amusement. When morning comes, their faces will be like those of monkeys and pigs."
