Musnad Ahmad 51:0

Narrated to us by Bahz, who said: Narrated to us by Shu'bah, who said: 'Asim ibn Bahdalah informed me, from Abu Wa'il, from a man, from his father, that he came to the Prophet (ﷺ) and said: "O Messenger of Allah, what is the most excellent of deeds?" He replied: "Faith in Allah." He asked: "Then what?" He replied: "Maintaining ties of kinship." He asked: "Then what?" He replied: "Enjoining good and forbidding evil." He said: "And the Messenger of Allah (ﷺ) said: 'The most hateful of deeds to Allah is associating partners with Him, then severing ties of kinship, then enjoining evil and forbidding good.'"
