مسند أحمد

It was narrated that ‘Amir bin Sa`d said: Husain bin Abi Waqqas said: l heard `Uthman bin `Affan (رضي الله عنه) say: What prevented me from narrating from the Messenger of Allah (ﷺ) was not the fact that was not the most knowledgeable of his Companions about what he said, but I bear witness that I heard him say: “Whoever says something about me that I did not say, let him take his place in Hell.” And he said: Husain was the most aware of his companions of what he said.
