Musannaf Ibn Abi Shaybah

Hazrat Ibn Aun (may Allah have mercy on him) says that I wrote a letter to Hazrat Nafi' (may Allah have mercy on him) asking about inviting the polytheists: so he (may Allah have mercy on him) wrote back to me that Hazrat Ibn Umar (may Allah be pleased with them both, may Allah have mercy on him) informed me that the Messenger of Allah (peace and blessings be upon him) attacked Banu Mustaliq while they were unaware, and their cattle were drinking water. And Hazrat Juwayriya bint Harith (may Allah be pleased with her) was among the spoils of war obtained from there. And Hazrat Ibn Umar (may Allah be pleased with them both) said: and I was among the horsemen.
