Musannaf Ibn Abi Shaybah 32585 — Reports on talk about rulers

It is narrated from Abdullah bin Buraydah (may Allah have mercy on him) that Sayyiduna al-Hasan bin Ali (may Allah be pleased with him) came to Sayyiduna Mu'awiyah (may Allah be pleased with him). Sayyiduna Mu'awiyah (may Allah be pleased with him) said: Today I give you a gift such as I have not given to anyone before you, and I will not give such a gift to any of the Arabs after you. Having said this, he gave him four hundred thousand, and he accepted it.
