Ibn Hanafiya reported,

If Ali had ever wanted to speak ill of Uthman , he would have done so the day people came to him complaining about Uthman's tax collectors. Ali said to me, "Go to Uthman and tell him that this is the charity of the Messenger of Allah ﷺ, so instruct your collectors to act according to its rules."I brought it to Uthman, but he said, "We have no need of it, take it away from us."So I brought it back to Ali and told him what Uthman had said.Ali replied, "Put it back where you took it from."

حدثنا قتيبة بن سعيد حدثنا سفيان عن محمد بن سوقة عن منذر

عن ابن الحنفية قال

لو كان علي رضي الله عنه ذاكرا عثمان رضي الله عنه ذكره يوم جاءه ناس فشكوا سعاة عثمان فقال لي علي اذهب إلى عثمان فأخبره أنها صدقة رسول الله ﷺ فمر سعاتك يعملون فيها فأتيته بها فقال أغنها عنا فأتيت بها عليا فأخبرته فقال ضعها حيث أخذتها
