Musannaf Ibn Abi Shaybah

Hazrat Ubaidah bin Jarrah (may Allah be pleased with him) wrote to the people of Deir Tayaya that I have granted protection to your lives, wealth, and places of worship, that they will not be destroyed nor broken, as long as you do not commit any new act or give shelter to a murderer. But if you commit any new act or give shelter to a murderer, then I am free from responsibility towards you. It is obligatory upon you to host a guest for three days. Indeed, we are free from the mistakes and slips of the army. Hazrat Khalid bin Waleed (may Allah be pleased with him), Hazrat Yazid bin Sufyan (may Allah be pleased with him), Hazrat Shurahbeel bin Hasnah (may Allah be pleased with him), and Quda'ah bin Aamir (may Allah be pleased with him) bore witness (became witnesses) and it was written down.
