Mukhtasar Muslim

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates from the Noble Prophet (peace and blessings be upon him) that: The Hour will be established while a man will be milking his she-camel, but the vessel will not have reached his mouth before the Hour comes; and two men will be engaged in buying and selling clothes, but they will not be able to complete the transaction before the Hour comes; and a man will be repairing his tank, but he will not have finished it before the Hour comes.
