Musannaf Ibn Abi Shaybah 40459 — Reports on Uthman (may Allah be)

It is narrated from Sayyiduna Sa'id bin Zayd (may Allah be pleased with him) that he said: I saw myself and the sister of Sayyiduna Umar (may Allah be pleased with him), when Umar had tied us both up because of Islam. And if a mountain were to crumble to pieces because of what you have done to Sayyiduna Uthman (may Allah be pleased with him), it would deserve to.
