مسند أحمد

It was narrated from Muslim Abu Sa`eed, the freed slave of `Uthman bin `Affan (رضي الله عنه) that `Uthman bin `Affan manumitted twenty slaves, and called for some pants and put them on; he had never worn them before, either during the Jahiliyyah or in Islam. And he said: I saw the Messenger of Allah (ﷺ) in a dream last night, and I saw Abu Bakr and `Umar (رضي الله عنهما) and they said to me, Be patient, for you will break your fast with us tomorrow. Then he called for a Mushaf and opened it, and he was killed with it in front of him.
