Musnad Ahmad Hadith 8824

It is narrated from Abu Huraira (may Allah be pleased with him) that the Noble Prophet (ﷺ) said: The Hour (Day of Judgment) will be established while two men are engaged in buying and selling with each other; the cloth will be between them, they will have spread it out, but the transaction will not be completed. Similarly, a man will have milked his animal, but before he can drink it, the Hour will be established. A man will have lifted a morsel to his mouth, but before he can eat it, the Hour will be established. And a man will be plastering his pond, but before he can water it, the Hour will be established.
