Musannaf Ibn Abi Shayba 33:351

Abu Mu'awiyah narrated to us, from al-A'mash, from Abu Wa'il, who said: Abdullah said: "I have not likened what has passed of the world except to a pool of water whose clear part has been drunk, and its dregs remain. And one of you will continue to be in a state of goodness as long as he fears Allah. And if something troubles his heart, he should come to a man and have him cure him of it. And by Allah, it is soon that you will not find him."
