Musannaf Ibn Abi Shaybah 4404 — Those who used to say: he does not

Nafi' said: Sayyiduna Ibn Umar (may Allah be pleased with them both) heard a storyteller reciting a verse of prostration before prayer had become permissible. The storyteller prostrated, and those sitting with him prostrated as well. Ibn Umar took hold of my hand, and when the forenoon (duha) came he said: "O Nafi', come, let us perform the prostration that those people performed out of its proper time."
