How sound is the Hadith: "The most unjust of people is he who feeds people to people"?

There is no hadith with the exact wording mentioned, "The most unjust of people is he who wrongs people for the sake of people." However, there is a saying from the scholars close to it, which is "The most unjust of people is he who wrongs people for the sake of people," attributed to Abu Yusuf, a student of Abu Hanifa. There is also the saying of the Tabi'i Muharib ibn Dithar, "The most unjust of people is he who wrongs for the sake of another." The meaning in both cases is: one who commits injustice for the benefit of someone else.
