Musnad Abu Ya'la al-Mawsili 115:240

Narrated to us Ibn Abi Samina, narrated to us Ibn Abi ‘Adi, from Husayn al-Mu‘allim, from Qatadah, from Anas, from the Prophet (may Allah bless him and grant him peace), who said: The servant does not reach the reality of faith until he loves for the people what he loves for himself of good.
