Musannaf Ibn Abi Shayba 3:5219

Waki’ narrated to us, Sufyan narrated to us, from Abdullah bin Uthman, from Ali al-Azdi, who said: Al-Hajjaj delayed the prayer at Arafah, so Ibn Umar prayed in his dwelling. Then some people stood up, and he said: So Al-Hajjaj ordered him, and he felt him (i.e., he was apprehended/seized).
