Is the following narration authentic?
“A man entered Jannah because of a fly, while another entered Jahannam because of a fly. “Two men passed by a people who had an idol, which it was not permissible for anyone to pass without making a sacrifice to it. They [the people] said to the first man: “Sacrifice [something in the name of the idol]. He said: “I will not sacrifice anything unless it be to Allah so they struck his neck (and he died) and entered Jannah”
Then they said to the second man: “Sacrifice [something].” He said: “I have nothing with which to do so.” They said: “Sacrifice something, even if it were only a fly,” and so he did so, and they allowed him to continue on his way and so he entered Jahannam”
