Musannaf Ibn Abi Shayba 33:608

Abu Usama narrated to us, from Mis'ar, from Ma'n, from 'Awn ibn 'Abd Allah, who said: While a man was in a garden in Egypt during the strife of Ibn al-Zubayr, sitting worried and sad, poking the ground, he raised his head and behold, there was a man with a shovel standing before him. The man with the shovel said, "Why do I see you worried and sad?" It was as if he [the first man] looked down upon him, so he said, "It is nothing." The man with the shovel said, "If it is for the sake of the world, then the world is a present commodity from which both the righteous and the wicked eat. And the Hereafter is a truthful appointed time in which a capable King judges, distinguishing between truth and falsehood." He even mentioned that it has joints like the joints of meat; whoever misses any part of it misses the truth. When he heard that, he said, "My worry is regarding what the Muslims are in." He [the man with the shovel] said, "Indeed, Allah will save you because of your compassion for the Muslims. And ask: Who is it that asked Allah and He did not give him? And called upon Allah and He did not answer him? And relied upon Him and He did not suffice him? And trusted in Him and He did not save him?" He [the first man] said: So I began to say, "O Allah, keep me safe and keep [others] safe from me." He said: Then it [the strife] cleared, and I was not afflicted by anything of it.
