Musannaf Ibn Abi Shaybah 40533 — Reports on Uthman (may Allah be)

It is narrated from Salamah bin Qays, who said: I met Sayyiduna Abu Dharr (may Allah be pleased with him), and he said: "O Salamah bin Qays, preserve three things. Do not combine two co-wives, for you will not be able to do justice, however eager you may be. Second, do not become a collector over charities, for he either falls short or exceeds. And do not go too close to the king, for however much of their worldly goods you reach, they will carry off more of your religion than that."
