Musnad Ahmad 30:1678

Khalaf narrated to us, he said: Khalid narrated to us, from Suhayl ibn Abi Salih, from his father, from Abu Hurayrah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Indeed, Allah is pleased for you with three things, and He is displeased for you with three things: He is pleased for you that you worship Him and do not associate anything with Him, that you hold fast to the rope of Allah all together and do not become divided, and that you offer sincere counsel to those whom Allah has entrusted with your affairs. And He is displeased for you with: gossip (he-said-she-said), wasting wealth, and excessive questioning."
