Musannaf Ibn Abi Shayba 13:840

Abu Bakr narrated to us, he said: Waki’ narrated to us, from Aban ibn Sam’ah, from Bakr ibn Abdullah al-Muzani, who said: I asked about purchasing Kharaj land with its water. He said: The Messenger of Allah (peace and blessings of Allah be upon him) forbade that you place upon your necks humiliation after Allah has saved you from it.
