Musannaf Ibn Abi Shaybah

Hazrat Abdur Rahman bin Ishaq narrates that I was present with Hazrat Salim and Hazrat Qasim bin Abdur Rahman when the governor of the city asked both of them about a man who had said to another: "O sinner (fasiq), what is the ruling about this?" Both of them recited this verse: "If a sinner (fasiq) brings you any news, investigate it thoroughly." Both of them said: Fasiq means liar; this person will be given lashes less than the prescribed legal limit.
