Musannaf Ibn Abi Shaybah 38798 — the first to do a thing, and who did

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said: The first to keep a dog was Nuh (peace be upon him). He said: "O my Lord! You commanded me to build the ark. I build the ark all day, then they come at night and damage it. Whatever work I do, they damage it. So when will what You commanded me be completed? My task has grown very long for me!" Allah Almighty revealed to Nuh: "O Nuh! Keep a dog to guard you." Nuh kept a dog. Nuh worked by day and slept by night. When the disobedient people of his nation came to damage the ark, the dog began to bark. At that Nuh woke up, took up a club and fell upon them, and they all fled. In this way Nuh succeeded in his purpose.
