Musannaf Ibn Abi Shaybah

It is narrated about Hazrat Jarir that while admonishing his people, he said: "You are like that ostrich which has been made to fly away. You should adhere to riding animals; if you do not find one, then make your own arrangements. And indeed, in terms of ruin, the very first land will be the one on the left side, then after that, the one behind on the right side. And the Gathering (Mahshar) will be here, and we will be at the back."
