Ibn Hanafiya reported,

If Ali رضي الله عنه were ever going to speak ill of Uthman رضي الله عنه, he would have done so the day some people came to him complaining about Uthman's tax collectors.Ali said to me, "Go to Uthman and inform him that this is the charity of the Messenger of Allah, so let your collectors handle it accordingly."I brought it to Uthman, and he said, "Keep 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."

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، فمر سعاتك يعملون فيها، فأتيته بها، فقال: أغنها عنا، فأتيت بها عليا، فأخبرته، فقال: ضعها حيث أخذتها.
