Musannaf Ibn Abi Shaybah 28145 — Those who disliked writing down

Ayyub said: I heard Sa'id bin Jubayr say: "We were differing over certain matters, so I wrote them down in a notebook. Then I brought it to Sayyiduna Ibn Umar (may Allah be pleased with them both) and asked him about those matters, concealing the writing, for if he had come to know of it, it would have been the cause of a parting between me and him."
