Musnad Ahmad 30:1573

Ishaq narrated to us, Ibn Lahi'ah narrated to us, from al-Hasan ibn Thawban, from Musa ibn Wardan, from Abu Hurairah, that the Prophet, peace and blessings of Allah be upon him, when he would bid farewell to someone, he would say: "I entrust to Allah your religion, your trust, and the final outcomes of your deeds."
